Heh… it’s nice to know that my features are being used. 
Anyway, you have some nice detailed geometry in there, in addition to some very well done textures (IMHO). Unluckily, it seems that those two things are never in the same place (i.e. the detailed geometry doesn’t seem to have much texture).
Also, it could use some shadows to add depth cues for the human eye to latch on to (you have to use spot-lights to get shadows, just incase you didn’t already know–which you probably did).
