That doesn't explain why the Sun has layers with radically different temperatures, or why the photosphere is so much cooler than the sun's atmosphere.
You can find various articles which get published every so often which claim to have solved it like any other major problem, but those are not the consensus that it is a mystery in Astronomy. There are "we solved it!" papers published practically every year or two, but the next year something will be published suggesting that it's a mystery. The official stance is generally that it's a mystery.
Even NASA's standard educational materials admit that it's a historic mystery that still persists:

Something mysterious is going on at the Sun. In defiance of all logic, its atmosphere gets much, much hotter the farther it stretches from the Sun’s blazing surface.
Temperatures in the corona — the Sun’s outer atmosphere — spike to 3 million degrees Fahrenheit, while just 1,000 miles below, the underlying surface simmers at a balmy 10,000 F. How the Sun manages this feat is a mystery that dates back nearly 150 years, and remains one of the greatest unanswered questions in astrophysics. Scientists call it the coronal heating problem.

I never said that it did. I simply asked a question.I doubt it would matter to those who already made up their mind about her credibility.For sure. Luckily, I'm not one of those people, so I'm not sure why you haven't yet laid out your argument for how accepting hush money for lying about something makes one more credible.
The image is somewhat inaccurate. The Sun is not brighter near the edges. The Sun is actually darker near the edges: A long standing mystery in Astronomy.
Limb Darkening:
Limb darkening is the gradual decrease in brightness of the disk of the Sun or of another star as observed from its centre to its edge, or limb. This phenomenon is readily apparent in photographs of the Sun. The darkening is greatest for blue light, amounting to a drop of as much as 90 percent from the Sun's photosphere to its outer atmospheric regions. Such limb darkening occurs because the solar atmosphere increases in temperature with depth. At the centre of the solar disk, an observer sees the deepest and warmest layers that emit the most light. At the limb, only the upper, cooler layers that produce less light can be seen. Observations of solar limb darkening are used to determine the temperature structure of the Sun's atmosphere. Information derived from such observations is applied in studying other stars.

Sun Brightness Inconsistent
Additionally, it should be noted that the sun appears to be inconsistently bright. This is curious, since in the Round Earth model the sun is an object where every point from half of the spherical sun's surface is reaching the eye of the observer. One should expect to see all parts of the sun's body with equal intensity, or with increased intensity at the edges, as intensity is defined by accumulated photons, and the number of miles per square arcsecond increases in those regions.
Find a photo of a Solar Eclipse, which are often taken through a solar filter, and then modify the brightness and contrast settings in order to bring out the areas of the image which are the brightest:
Compare that to the hotspotting seen in a projector's image on a screen:
Source: Hotspotting or brightness inhomogeneity
The hotspot seen in the sun may suggest a projection upon the atmoplane. Projections, such as from a projector shining on a movie screen, tend to have hotspots in them.
Inconsistent Brightness: A Round Earth Mystery
The inconsistent brightness is a problem in RET, and it is well admitted. Astronomers find difficulty in explaining how it works to have outer layers of the sun significantly dimmer than other layers.
Astronomers had to make the surface of the sun, the photosphere, very cold—at only about 6000 degrees Kelvin, compared to the much hotter atmosphere of the sun called the Solar Corona that is about several million degrees Kelvin, which is seen as a wispy aura around the sun seen at Total Solar Eclipse or with a coronagraph; and also significantly different compared to 15 million degrees Kelvin for the Solar Core (Archive). In addition, astronomers had to make the outer cool photosphere layer transparent or semi-transparent so that the radiation from the core could pass through it to the observer.
Article: Solving the Mystery of the Sun's Hot Atmosphere:
“ The Sun's surface, the photosphere, has a temperature of around 6000 degrees, but the outer atmosphere, the corona -- best seen from Earth during total solar eclipses -- is several hundred times hotter. How the corona is heated to millions of degrees is one of the most significant unsolved problems in astrophysics. ”
“ Why the Sun's corona is so hot is a long-standing puzzle. It's as if a flame were coming out of an ice cube. It doesn't make any sense! ”

“ Spots Apparently Change Their Speed and Form as They Pass Across the Disk — A spot is seen on the eastern limb; day by day it progresses, With a gradually-increasing rapidity, until it reaches the center; it then Slowly loses its rapidity, and finally disappears on the western limb. The diagram illustrates the apparent change which takes place in the form. Suppose at first the spot is of an oval shape; as it approaches the center it apparently widens and becomes circular. Having passed that point, it becomes more and more oval until it disappears. ”
That said, your question is very non-specific. You want "an explanation for why the sun looks the way it does", which honestly gives us absolutely nothing to work with.
Please explain your argument (presumably in favour of RE?), and clarify what it is you'd like to discuss.
