The only part of his design I don't like is his boring face and hair. His hair is a bit better in the artwork but it's straighter and highly generic in game.
Otherwise I think his armor is fine and hearkens back to old Amano designs, which, the more whimsical and fantasy like, the better IMO. It has a little bit of a modern flair to it but this game looks to be more fantasy than modern which I love to see.
Also pleased with how good it looks on mobile. Hopefully it is highly reviewed and gets more people into playing games on Android/iOS, and more developers into developing quality titles. I'm tired of having a sleek, incredibly powerful device in my pocket, but having all the high quality games developed for severely underpowered dedicated handheld gaming consoles that are bulky and that I must carry around in addition to my sleek powerful expensive device. Google Play Games and iOS Game Center are there. Controller support is there. Let's get this thing going.
