Redesigned Characters

Those of you into video games and comics should recognize these characters from the get go, but for those of you who aren't that familiar they are:

-Bowser from "Mario Bros"
-Green Goblin from "Spider-Man"
-Venom from "Spider-Man"

Since I'm practicing on Character Designing, I figured I'd take existing characters and redesign them in my own style. These drawings were done earlier this year but I've touched up the painting further and smoothed out the line work, enjoy!
