Here is my champion, a Thunder Demon !
I'm open if you have any advices !

I tried with different colors...

Really like the design on the character and how his wings frame the image!
Both the first and last one have a much colder color scheme to them, which works well for him I feel. Personally, I like the last one more, because of the warm light in the background. It just makes it look more appealing to me. : )

Thank you, I prefered the last one too ! Now I am fixed thanks to the two of you ! : )
