Loved the design! I think the usability is smooth; I didn't have any problems creating the character. The only part I found a little odd was the color icon, but overall it's great!
The music reminded me a lot of some NES or SNES games.
On a more personal note, I think it would be nice if there were more curly/short hair and beard options hehe. But in general, I loved the character styles! Can't wait to see more of the project!
