Here is my take on Gamora as seen in the more recent Guardians of the Galaxy books. Specifically, I blended her look there with the one from The Thanos Imperative. I dremeled and sculpted the heck out of a DCUC Power Girl figure and gave her new hair, straps, boots, etc. etc. The straps, skulls, "chain", crown and holster are mostly done using a combination of apoxie sculpt, fix-it, and fodder.
I painted her using Citadel undercoats and then topcoat mixes of various Citadels coated, drybrushed, recoated, drybrushed, recoated, so-on for what seemed like a thousand hours until I had all the tones I wanted. Her eye makeup and the other finer details were done with a brush and also Gundam markers, both ultrafine.
Only the energy pistol is stock--every other piece of her gear was customized. I gave her a poseable hand and removable cape, which also features a slot for bladed weapons. Three blades are pictured here--her legendary shiv Godslayer is almost invisible, try to spot it on her back in the second pic wedged between Godblade and the right strap of her costume!
