Not bad. But the blood needs to stay longer in the air. Like the stick figurs are, more particles would make it more realistic. Also I don't quite like your style, don't make punches flash every time, and in the air, it looks wrong. make a new style.
I like this style.. im in the stages where i have only made afew anims with it.. With practice it will get better.. besides i think its alot better than any other style i have used.
Well it just looks overused, you overuse powerful flashes, when hitting, like every time. It's nothing new and will get boring after time. Well it's your choice.
