Well you said in the background story what first came to my mind. Secondly, Frost's side of her stomach looks a lil weird, glitchy almost. Nice job in making her from the sub-zero sprite tho. 3/5
I think its too simple. I cant really tell what frost and sub zero are doing to their opponent. Frost looks too manly and big. The background could have been different, could have made it more original.
The Frost sprite needs a lot more work. My advice is to play around with female sprites. For example Kitana body with Sindels torso. Stuff like that. But you need a better art program. I suggest you look for art programs in your school. That's what I did and found some.
