This is a very creative character concept! I once saw an article which mentions a villainess made out of puzzle pieces which Superman fought, and that article is about villains with underwhelming superpowers. Not associating it with your work or anything, but it's just something I read.
Just saw this and the old saying "Great minds think alike" comes to mind It's a coincidence that we came to visualize such a concept so similarly: I have a character just like that (and it's a femme too!) but mine is more focused to a dark fantasy scenario, whereas yours is more whimzical and fun (the jigzam flower ). I really liked your vision and concept. Nice work and concept
Regarding critique... well, I can't really say anything: the color selection is great, the pose and moment you depict is on spot and the concept... well, you know what I think about it
Wonderful piece. And very interesting as always! The concept of fitting puzzle pieces together to make a picture... that always boggled my mind. And here you seem to have created a picture by piecing puzzle pieces together to piece a picture of puzzle pieces.
