not sure if to be flattered or annoyed.

The Favourite would suggest flattered. Although if I were being extremely picky, I'd notice that my enjoyment of the camo pattern stems more from the fact that it looks as if it's flat, like they're a window into Tetris Land as the design doesn't seem to sweep with the curvature of the shorts themselves.
Frankly, I think it makes them look better like that for said reasons.

for a 20$ flatcolor commission I didn't bother moving from PaintToolSAI to Photoshop to to warp

If I was gonna do warp I would do shades/etc. as well. :3
