I'll be sure to give feedback to you
-Android 18 sprites are still there;
-he also hasn't a palette;
-sprites are good but I would suggest changing the stand sprite, because like Trunks he seems to be ready to get his sword, but 17 hasn't one;
-sprite problems: the hair is connected to the black T-shirt;
-strong punch sprites are used too much times;
I'll tell you more later, if you're interested.
