Rowwrr. Check out my lil' tuft of chest hair. Bless you, Sculpey.
Blanka-- the first of my SF2 figures. An X-men vs. Street Fighter Sabretooth that's been thoroughly sanded, Sculpeyed, and painted.
Vega figure

Vega. One of the better customs I've done. You can't see, but his hair is long and braided in the back, just like the character (Have you ever tried to braid Sculpey, or any clay, for that matter? Don't.). This was a Spider-Man Tarantula. It's neat.
Sakura
Sakura. The scan turned out poorly on this one, but in real life the figure looks pretty neat. It was an X-Men vs. Street Fighter Rogue with Sculpey for hair and clothing.
Juni and Juli

Juni and Juli from Street Fighter Alpha 3, a game, by the way, which you should be playing right now. Both of these girls came from X-men vs. Street Fighter Cammy figures, with Sculpey hair. These two are the fastest customs I ever made; I finished both of them in less time than I've ever taken for a single figure. So these either represent a remarkable fit of creativity or a rare lapse in laziness, however you choose to look at it.
Yahooey!
Ra-shuu! Yahooey! It's Dan, who, sadly, has no voice chip to properly express his brilliant taunting. Dan's base is, strangely enough, Akuma, with resculpted hair. I dyed Ryu's gi with a mixture of red acrylic paint and water.
