Look up work from Vincent Ptitvinc. (http://ptitvinc.deviantart.com/gallery/?offset=0)
He did some incredible work, such as this;
this;
this;
but most importantly, this;
That last picture is featured in the "Gossamer Worlds: Glimmer Gloam" Tabletop RPG, and it is EXACTLY what you like, with a hint of fantasy as well. If you really want some more pictures like this, I could try recommending you some free tabletop RPG's, and you can check out the art work there, as well as the artists.
I understand that that may not be your thing, but nabbing the free stuff just for the artists names to look up is worth it. On http://www.drivethrurpg.com/ there are about 1000 free supplements with 3/4 of them that have excellent artwork. It's worth it to check it out.
At least, that's my two cents.
