For now I'll stick to this one and keep refining it. BG colors are cool and make a good contrast with the character in white.
I will also have to change the pitch for the contest because everything changed.
I will later refine the character so he can fit with the composition and the story behind it.

Just one little detail that is bugging me...the "crown" looks a bit too much attached to his skull maybe ?
Can't wait to see the result and also explanations on this !
Is he controlling spirits or galaxies or something ?

Hey, thanks you're right the crown is too low on his head and don't seems that it's flying ^^'
I'm focused on the bg details for now but everything on the characters is subject to later modifications =D
Yeah something like that, I was thinking about a gigantic entity how's crushing galaxies to avoid the Universe expansion. In a sense he's good because of that, but for his residents, he's an unstoppable power of destruction how could one day destroy entire solar systems or galaxies to maintain the balance of the Universe...
