Wow, these are really good. You've definitely improved.
'Couple of things to fix:
00 Alternate - the 'Rappers' on the ass isn't centered
90 Alternate - The logos aren't good, the ones in the middle will be cut off on the shorts. Maybe do them like trim up the sides?
EDIT: And the rectangles are missing. The three rectangles at the top of the buni are the insides of the shorts, you need to have them the same colour as the shorts and if there is trim, the same trim as well.
