Some GUI elements C+C

I've been working on some basic gui elements for a game I'm working on, so far I only have one concept piece:
here is the split up sheet which is on a 32x32 grid

sorry for the excess blanks space the sheet is 512x512.

here is a concept piece for a skills menu no text because I haven't any font ideas and I also have no idea how to make skill icons for the far left boxes:


C+C would be nice, and I'd like to see what you'd do differently...or maybe some other menus
