mrr... i went through all the work of making a quick mockup of how well a metroid sprite could still look at 32 pixels tall and then you guys have to go and convince him to resize everything without me...
Ti-DkS: when i saw you wanted 24*24's i quickly resized the samus in the pic i made to fit that. i could do the others if you want(although there are several people here more qualified for that type of thing than i am). good luck on this project!
Nice job with Samus, I just don't like the head (is there a head?)
