I got two littel things.
You need to twist your forearms a littel bit. The Coverstrips must be in one line frome bizeps to forearm.
And your Pauldron looks al littelbit thin and not so puffy. It looks a little bit wrinkelt. I hope you know what I mean. Don't know the correct english word for it.
What kind of material is it? It looks like vinyl or something like this.
By the way, I like your weathering. Looks nice.
