Heehee, I can only say one thing: vector = pentool. No pentool; no vector ;) Try to learn it a bit more... the pentool is your friend ;) The vector's actually really good except for a few jerky bits on the hair :)
i spose he just doesn't look evil enough in this wall lol~ I guess, perhaps if he looked like really sly.... *wahahaha* hummmm.... something more coula been done with the background though. Kinda empty~ not techy enough for me. When I think tech I think lots of numbers, letters and really really square objects- sharp lines. Lol. I think this might have even been more interesting if you put him on a box or something with the radioactive sign and it says "handle with caution" or perhaps has that as a warning label XD
Nevertheless it's a good wall to take your mind off the w.a.r :nya:
Kudos!
