For texturing, it sort of reminds me of the ship from episode 1 haha, you could chrome it out. I think that as sleek as it is it doesn't need a crazy texture, maybe a procedural and just model some more components on it and have them textured differently to make it more detailed. Might make a simple texture less obvious. Then maybe do an AO pass with the distance set really high and use that as the wear in places where parts touch. Just a though, hope it helps.
