Coming back to scratch...there is too much things I don't like about this character anymore...
Although, none of this thumbnails are to my liking...I need to push a lot of concepts, and first of all simplify this...I was going too deep on my concept but in the end I had very hard time finding how to ilustrate my first villain...(and also 1 very distinctive power on the canvas...)
Now I'm thinking doing a child or a woman (or even maybe a mecha/mix/fuse)...still very confuse where I want to go...we'll see ^^' (with many many thumbnails)
Thanks @Pregium for the good insights about it (silhouettes and powers).
We have to keep in mind, judges need to understand in quick moment what the power ability is from our heroes/villains; the first of all concerns.
