I like the face attached to the body. I think it would work nicely for what you have planed.
As for the body it's self. (since I know Who you are basing this OC off of) I would say make the hips & chest a bit bigger. You gotta remember Spazy has a LOT of curve & her own flotation devices XD
That & it would make the boob jokes a bit more funny.
I also like the from behind head. Nice shape to the ears. Very much like a yote.
The other faces are still a bit ify but only cuz they were quick roughs & don't have the clear lines/final adjustments put down yet.
Over all, a very good start
