Got more.

R-Type (taken from the arcade)

Darius Silverhawks (taken from the Super Famicom game)

Radiant Silvergun

The F-14 Tomcat from Sega's Afterburner on the X68000.

A cute rendition of Kasumi from Dead or Alive I found by doing an image search online.
OK, hold onto your butts.

V.I.N.CENT from The Black Hole. I took the sprite from a user named Mazeon on Tumblr. He liked it.

Yohko from Devil Hunter Yohko on the Megadrive. This was my first time making something with Nano Beads, which are 1/4th the size of regular Perler Beads. My first time using these tiny beads was a very HUGE project! At one point, I bumped the trays and messed up so many beads and had to redo all the work on them. Since these beads are so tiny, they can be disturbed far more easily. Yikes!

Captain America from Marvel Super Heroes: War of the Gems on Super Famicom. It's the largest one I've made yet, and he is about as tall as Yohko next to him.
