It looks good (and although I hate the phrase) especially for your first skin. Just a bit of work and you'll be a pro! Clever job with the "R" on the chest. My only real criticism would be to get the face a bit better. Maybe work with one already from the game? The nose you're currently using is a bit funny looking (from the screenshots anyways.) That won't even be a problem in most gameplay though so the point remains: Good job ^-^ Keep practicing 
Thanks so much! The nose issue is with the face on the Moon Knight model, since his mask makes it kind of flat. I really would need that custom model for that. I actually pulled the face from the same pic I used for the HUD, and I'm not sure if any original character has the proper face for that... I'll look into it.
It looks great! 
You just need to darken the red part the moon.
Thanks man! I'll try to do that.
EDIT: Did it. I think you were right; blends in better now.
