Wow! Now I wanna play it! Nice work! But there should be marks in the buttons like A, Y and so on...
hm, the directionpad looks a little hastily done, it might be better if you did some more straight lines. :)
the light glare lines on the lower half of the ds could really benifit from AA
Very nice! Some details may be missing (like the letters on the buttons), but I think the shading is fatastic.
