To be fair I had to google an image as I never played the game myself, but none of the screenshots I saw included a similar HUD.. So I figured I might as well post that screenshot.
Anyways, back to the point.. I agree that the metal bits may be a little bit on the bright side, and the top right blue edge appears to be cut off near the end.. And as for the blue squares on the left, it might be nicer to move them down a little and put them horizontally and perhaps a little smaller to simulate your health, and show what gun you're using on the other side of the viewport.
Back from the dead!
