not to gang, but im with lief. anatomy and physics are always of the utmost importance, even in a stylized piece. as far as anatomy in this piece, i wouldnt know whether to say its a bad hand or a bad foot or a bad potato, so theres no sense in critiquing on anatomy.
if part of this is riped or edited, im asking as an artist that you give credit to origin of it. i cant make you, but if you did rip it and didnt say so, thats still an insult to the creator and the rest of the art world
the blast i think should be made directional, and a lot m,ore like light. atm, its looks scribbled in paint, and it has no lightlike qualities. you may want to add lighting effects on the whateveritis as the blast happens, and lose that odd blue outline.
