Serenity: Part of it is the angle the screenshot was taken.
Another part might be that in-game you are flying with 3:4 ratio and it's stretching to a widescreen monitor, heavily distorting things.
I think TK did a good job on the artwork of that skin, but that it looks too washed out. There are photos of it that show there was a winter paint scheme but that the art was crisp and clear, and it wasn't so heavily faded. It just looks different. A good skin, but could have been better.
P.S. Snefens, tubby usually means more "fat" or "squat" or "rotund", not so much "lumpy" or "bumpy"
