Besides the sun fluctuating in size out of proportion to their distance (up to and including increasing in size between Uranus and Neptune)?
The apparent size of the sun in an rendering/painting depends on the angle of view the painting/renderings are meant to depict, no?
Without knowing how wide the field of view is meant to be, it would be impossible to say whether the sun is depicted too big or too small?
The only painting in the thread that gives an clear indication of its intended field of view is one from the surface of Pluto. Here the visual size of Charon in the sky tells the field of view. Charon should substandard roughly 3 degrees of arc when viewed from surface of Pluto. The sun should substand 0.01 degrees. So the sun looks distinctly too large compared to Charon from the perspective of Pluto. However, the apparent large size of the sun in the painting can still be chalked up to glare. Even if the sun would almost be star like in size when viewed from the distance of Pluto, it would still be a blindingly bright point of light, almost like staring down a laser pointer. Staring at it would still damage your retina. It would certainly be haloed in glare. So it is still hard to say the image is truly inaccurate.

And no, you don't need a surface to see a beautiful view of the sun, but it certainly helps for the sort of photos we come to expect from the first four images, especially if we want to send a probe to someplace like Jupiter to see what the view is like from there.
Yes, but clouds seems to be depicted as floating beneath the ring, which is as it should be. The ring would be an exoatmospheric feature, a background to the image of high clouds when viewed from inside saturn’s atmosphere.
The painting also captures the sun dogs, which one would expect from refraction caused by water and ammonia crystals in high Saturn atmosphere. That is a nice touch.
