it looks almost aquatic, slightly starwarsish. I believe based on the shape and hull lines that this would be best suited as an amarrian design. just splash some shiny gold paint on that bad boy and it's good to go!
the simple way - to take one picture (texture) you like, and wrap it over your rendered model in pshotoshop. Transform>wrap. Play with transparency and blending mode (as i mentioned - overlay or softlight) A lot of fun and quick result.
