SO I finished gluing up the helmet but its crazy tight in the front so its scrunching my face haha so i'll have some close up pictures of it once it fits right. However as a bonus I decided to show my near finished chest piece and gauntlets, but as you can see they still need some fine tuning.
You're going for Frank Miller's, right? (Pardon the cat.)
Because I think you're on the right track! I did notice a few things I might work on:
The shape of the eyes is a bit surprised (!), and would likely benefit from being a third of the size, to give them that menacing, sliver look.
And because the helmet is so large, you may to bulk up the rest of the armor to balance things out. Maybe a little more heft in the chest, a heavy duty collar/gorget, and some big, tall shoulders to really make a solid base.
You've probably seen it, but this is figure is also a great reference for the eyes and bulk:
