This was pretty fun. I asked people from twitter (my account is https://twitter.com/DosanDusk ) for suggestion for characters to draw, and these were the chosen ones.
1: Hyena Mozoo from some super sentai series
2: Foxy from FNAF
3: Zorori from Kaiketsu Zorori
4: RedXIII from FF7
5: Cornell from Castlevania
6: Scias from BoF4. Literally the best character ever, I simply love his design and animations.
