There's some areas near the fighterbays and the reactor that has randomly-lit blotches of hull,
with a gap in between the windows and the acclaimed patch, as mentioned by Kolgena, I do like how it looks on the neck though.
Actually I can excuse those for some reason I can't elaborate but I know what it is...something with eclipses.
The problem with the patches I just found out is that there's very little in gradients, it's just there and then suddenly it's gone.

The amount of light striking the hull should be less intense as it goes farther out, instead it looks completely even until it reaches the one point where it abrubtly vanishes.
