They look cool and all, but what about different animals. When it came to "OCs", I always wanted to point out that there are animals other than hedgehogs that can be used, and those might perhaps make the character a bit more original (since they are, after all, original characters). There are lots of animals (elephants, bears, tigers, etc.) that haven't already been used by SEGA. I myself don't make fan characters, so I guess I wouldn't really know much on this subject. Just try to use different animals (if you want to) and maybe get rid of some of the clothes. Most Sonic characters don't wear clothes, but it's up to you.
