Yeah, I was going for a PM inspire pose instead of a traditional one, but it came out weird.

I like them all. Specially that punky cheep cheep.

 Nice. I'm more partial to the cheep cheep actually, because the boo seems sort of misshapen and jaggy.

They're great! Do more! 

Well, any ideas of how I can fix it?

 My fav is the Magikoopa. Very smooth.

I think they all look excellent, especially the boo!!

 I like it, nice lines.

very nice!!!...I like them very much... I agree with Boo..nice take..

I don't like the Cheep cheep, but the Boo and the Magikoopa are really smooth and Mario-y.

I really like that ghost! A very original take on it!
