Goku Fan Art

Hi guys, here is the newest fan art design I made. It's a personal project since I want to practice my "new style" for coloring. Since I don't include the line arts anymore in my design, I am experimenting if whether or not should I add a stroke around my characters. So far, for this particular character, it does look good. If you have any comments or suggestions, feel free to tell me and help me improve. Thank you in advance.
