Nice animation, I think you should add more frame to the stance and make the transition back to Ben 10 also with the green frames.
That would make a more smooth loop.
Completely handmade :)
EDITED* maybe I misunderstood ^-^;
if you mean the scene that combine green color and the character , that one i use 2 layer with one is character and another is green layer and lower the green layer opacity.
Is this entirely hand made? or did you use a filter to "tween" between the normal collored and green layers?
Nothing is wrong what you did for the FX for a game project or whatever you made this for.
However, Pixeljoint wants all pixelart to showcase 100% pure pixel powers. Will you please remove those FXd frames and maybe link to this hybrid in the description if you don't care to make those frames by hand for the gallery. You can also explain in the description that there is a full animation with words too, thanks.
Nice sprite btw :)
