Impressive.
But here's the things you could improve on (I'm not sayin I could do better, I'm pointing it out as a viewer)
It would've been awesome if the color of the armor wasn't so different from the theme of the environment (Dawn/dusk).
Some random lines on the HUD(a crosshair perhaps) would've been a nice touch.
Lastly the gun could've been in the other hand pointing towards the left corner and possibly shooting.
But then again I'm just pointing out the things that would appeal to me, what may or may not appeal to others is a different matter.
All in all it's a job very well done.
