Since many of them arent in 128x128, its hard to really see what they would be ingame.
But as of now
1. Is probably the cleanest : 9/10
2. Is ok, not much improvement from current design : 7/10
3. That is a work of art. But hell no : 3/10
4. Very nice one, good change of color and respect every aspect needed 9.1/10
5. To much disparity in the design : 4/10
6. Wrong weapon or class ? But seems to be very cool and would probably be the best improvement : 8/10
7. Different colors, look to much similar to best team : 7/10
