Megaman X

just further practice with photoshop. tried a different way of doing the line work by using the actual sketch and coloring it rather then tracing it in photoshop (which with a mouse is an extreme pain) then coloring it. i liked this way better but as u can see in the face area i just need to make my sketch cleaner and darker any tips or suggestions would be appreciated, thanks. This is obviously a character that belongs to CAPCOM and not myself, used the game case to reference this. All my art looks so flat i hate it >< i don't know what to do.
