Thanks for your compliments and suggestions!
Unfortunately I didn't draw the characters or the background (I can't draw nearly as well as you!). My contribution is limited to lighting (Making use of existing lighting, and adding new lighting information where necessary. i.e.: the lightsabers and their light emissions, and ambient occlusion + shadows from the characters onto the background scene), composition and color correction.

Background from Star Wars The Old Republic, by Bioware."
These are two friends of mine in costumes who were photographed by Manu Binder during a Star Wars themed freezemob event (unfortunately the Original Photo
was on a friends-of-friends-only Facebook page, so the link might not work). So they look like they're standing still, because that's exactly what they're trying to do ^_^.
The background is a screenshot I took in Star Wars The Old Republic, with some lighting tweaks and color balance.
