I think everyone agrees that something similar to the Ranseur/OC snubline is the way to go as far as textures are concerned.
Spazzy is correct - the thing has too many windows, but the (edit: updated model, not the original) gaps aren't bad IMO. Makes it look unique, somewhat otherworldly, which is exactly how a 'other human' faction should be represented.
See this link for further suggested changes. You're doing great, keep it up!
