Steampunk GW2 Wallpaper

I'm working on a wallpaper for my new PC, and.. oh yeah!!  I got a new PC.  It's a lot faster than my previous one, with a much better GPU.

Anyways, back on topic.  The wallpaper.  I really like the Steampunk look, and wanted to incorporate my other online passion of GW2, so here is what I have so far.

I want to add more detail, so it's look awesome, and I have no time limit on it, so I can experiment as I go, and swap things up as my skill level improves.
