Republic Commandos RC-1138 and RC-1207, better known as Delta Oh-Seven Sev
and Delta Three-Eight Boss
As you can see in the above link to the inks, this was actually a part of the Scorch image, or rather was later added. I stumbled upon this on Jeff's current art thread on Rebelscum, and immediately asked him to send me a hi-res that I could color. And well, here it is.
I split it from the Scorch, Boss and Sev image because I would have to create a new background for Scorch, and I actually very much like this. Also, my style has changed a bit since Scorch, so maybe it wouldn't really fit, anyway.
