Looks great!
Love the big thumbs, but their filesize should be smaller - they slow down the load. So do the POTDs - you can textlink them and link more.
Link your best trades on top.
List your best sponsors in some textlinks - most surfers do not signup from galleries but mainsite links (if you have them).
Use target=blank.
Put some meta keywords in your head section.
Install an emailform instead or post your email in a gif (otherwise you might risk spam)
If you need more teensponsors, check my sig.
Good luck
