Awaiting the colored versions to come...overall I would just make the pores a little smaller and try congregate them near the the nose...and the bridge.
You should check out the Chateau de Chenonceau, my favourite Loire Valley castle, it has these two bridge-galleries, with a similar lighting, might help you :)
They should also only use 30cm CRT screens on the bridge, right? Constraining the design because of a 30+ years old movie is what I'd personally call silly...
what process did you use to remove the geometry to create the four slanted ovals above the grips in the side of the gun. Booleans? Delete faces and bridge? just wondering.
