M&L:PJ styled customs

It's been a long time since I've done serious sprite work, so I figured I'd ask for some tips and insight on my current project.

Basically I'm working on a free-to-play Smash Bros. RPG and decided on the sprite style of Mario & Luigi Paper Jam/Dream Team since I really enjoy the look. So for starters, here's Lucas in the style. I do see things I could do to improve it, but some outside opinions and pointers are wanted of course!
