I'd say Metal Sonic is you're best import. Why? Well first of all you worked really hard on him. You made many versions of him till you got him right. The rig is near perfect. SDo0m loved it. Truly you're best import in my opinion.
If you still want suggestion well i can give you some more. Hmmm ... well i know we already have her in but what about UMvC3 Chun-li DLC/Alpha outfit over Zelda, you know:
It would be really nice, this outfit is my favorite XD! If possible adding facial expressions (or at least the ability to blink/ have close eyes) would be great. Why over Zelda btw? Although Sheik seems more fitting for a Chunner in a skin thight suit, Zelda will have a Chun-li PSA over her.
Hell, if you can somehow "update" the GBC model port (which is a merge of both TvC and MvC3 model) by making it only MvC3 and have facial expression that would be freaking dope too.
Unfortunatly, I don't have the model link anymore (Demonboy apperantly got rid of it). He would probably give me back the model if i ask him, especialy if you're interested.
Leon, I understand what you're feeling. Yeah, I'm not a stage importer like you guys. I make CSP's, I sometimes loose interest too. I stopped for a long while ago and I got my interest back. Besides, you deserve a break
Dat stream was epic. Sorry I laughed when it froze, that was me being an ass. It wasn't funny at all. Did you ever get it to work? I'm joking, that was [censored]ing hilarious.
