Artwork from a youth's fantasy book I'm making dealing with limitless power and finding maturity.

Hey guys, Just wanted to get some feedback and opinions on my new children's book concept. I am aiming for a modern, visually fantastic art storybook that teaches kids the value of hard work and growing up.

Here is the image, let me know what you guys think!

Ideally this is for the kid who loves video games and the parent who wants them to get involved in the real world xD.
