I prefer PS2 models since they can be used in XML2. But I think you used the right models. No PS2 model would have looked right. And you actually managed to give each skin that distinct something that makes them look as Iron Man and War Machine. Good job.
Thank you, hemlot! Sorry I couldn't give you XML2-compatible models for those.

Hyperman,
Wow... totally amazing Iron Man mods!!

I know you probably have a lot of requests, but I'm a big Iron Man fan, especially the movie versions of his armors. I was wondering if you could use the MUA2 model of Iron Man to kind of make some skins that resemble some Iron Man armors I think would look sweet in MUA.
My first request is for a version of the Ultimate armor, but from the Iron Man 2 Hasbro figure line #18 - Ultimate Armor (pictured below). Basically they used the Mark IV armor from the movie and designed it to mimic the appearance of the Ultimate Iron Man armor. I think its sweet!

The second is a version of a custom of the Iron Patriot armor done from a Mark VI statue. I think this would also look awesome in-game!

Just let me know what you think, but awesome skins! Keep up the great work!! 
Thanks! The movie versions of the armors are my favorite too! I also liked the Bleeding Edge armor he's got in the comics now; it's like the movies too.
I'm thinking about doing what I can to make the MUA2 model look like a couple of the movie armors. They have a lot of detail to them, so it could take some time. I've also got some Green Lantern skins I'm planning to make, so it could be a while until I can get to that. Once I finish my planned Iron Man skins, I'll see about making your requests, so keep checking back! By the way, what'd you think of the jumpsuit Tony? I based that on how he looks in the game based on Iron Man 2.
Plans for Iron Man Movie armors:
Mark I: not unless I can find a sufficiently large and crazy model that looks like it.
Mark II: Definitely.
Mark III or IV: one of these 2.
Mark V: Probably.
Mark VI: Probably.
Mark VII: Possibly.
I'll see about the movie-based Ultimate and Iron Patriot. I think Iron Patriot's more likely, because the Ultimate just looks kind of dull.
I put info on possible skins in the main post along with current and definite future skins.
