Hoi hoi! I'm new to this site, and I've got my first real attempt at some early concept art. A "Native American Shaman" wizard character. I had chosen this character theme after a friend and I spun a wheel of different themes and landed on this. If you have thoughts on my work, please feel free to let me know!

It would be more helpful for us to know what are your plans for the character. Because if it's for a game, then our inputs will be more inclined to gameplay. The same goes for movie, comics, animation respectively.
Great work so far!
