Gengar Things nobody notices...
I've got to say, I agree with you on the Cheshire Cat being the Basis for Gengar. However you made him a little too much like the Cheshire Cat and less like a 'ghost' of him. The blue you used was probably what did it, but that's just my veiw on it. 9/10 5/5 (becuase of the relistics and the fact that it IS very good)
