Steampunk Rifle Textures

So I've finally have some halfway decent textures applied to my rifle that I posted last week. Not much to say about it really at this point. This isn't quite finished yet; I've only just thrown some simple materials on it today. I haven't added any grunge or dirt and the emissive green texture isn't sitting well with me. I want to spend a few more days getting the materials and textures right before I call this finished. I'll post final renders next week.
