This was really good. It's like watching someone who started and is only getting better. With that said I do really love the flash parts. With that said I can't lie I can see if you ever wanted to move from Sprites to Flash, that it would work out.
I mean a story this good, about the only way I could see it not "looking" good is if you said the hell with it and went to classic stick figures XD
anyways Good job to both you and the cast!
