I think that modelling and mapping looks very good already.
Imo, what will make the biggest impact will be the "wearing" of the textures (that can wait the final step, of course). At this point everything is too perfect, too new. There is no dirt, no scratch. Even if this would miss in real life, it's still a good idea to include it, because it adds to the realism; or better yet it breaks the perfection.

And this one (one of my favorites, to explain the basics): http://bct.me/tutorials/realistic-texturing/
But you can ignore it for now, it is something that can be done at the end. By you, or by a texture artist willing to help
