1. The corona should be less chaotic. The gas appears to follow the Sun's
magnetic field lines.
Here is a photograph of the 1994 eclipse that has been processed to bring
out the detail. The contrast is somewhat exaggerated, but it looks much
more like what our eyes would see than an unprocessed photo. (I witnessed
this one myself, so i have a feel for the comparison.) In this photograph,
the coronal structure appears atypically streamlined, but even at other
times, the magnetic structure is obvious.

The "bleeding" effect around the limb of the Moon is very realistic,
however. You should keep that.
2. The Sun has long streamers. The above photograph is a good illustration,
because the streamers were unusually long at the time. You can see them at
5, 10, and 11 o' clock. What you can't see from the photo is that the
streamers were visible to about 6 degrees (12 solar diameters), IIRC, on
each side of the Sun. If you haven't seen a total solar eclipse yourself,
you may not know about streamers, because photographs are notoriously lousy
at picking them up. The Winters did a *very* good job of teasing them out
in this composite.
3. The Sun has glowing red prominences. These are huge arcs of gas that
fluoresce at 656.3 nm. Prominences were not prominent during the 1994
eclipse, but two small ones, at 4:00 and 4:30, show in the photograph.
