the problem with the popping on his pants is that since that's a simualtion, the cloth reacts to liu's actions, let me explain it.
before he jumps, liu is on his fighting stance, than he jumps, due to and sprite count, I can't have all the necesary sprites for the pants to go back to it's inicial position cause it will need at least 10 sprites more, and there will be a lag in the transition between his jump animation to any other, but I'm pretty sure that when those pants gets painted in black, that popping won't be seen.. I'm a 100% sure in the gameplay we won't see it, that's why I will stop making animations and I will try to get the pallete right and all those sprites in mugen.
fight stance
moving forward-backward
ducking
jumping
@bleed, I will try to get his hands to look right, even though I have to be slightly different than the sprites
