While not having previously been familiar with art by Benjamin, I can certainly commend the live dynamics of this near-bare-breasted heroine armed with an impressive automatic rifle in the midst of a dashing retreat from a promptly impending air-bourn chopper.
I decent study of the original artwork's scan in comparison to the revision wall art submits the use of a vector-style filter (that's taking a rough guess, lest the work was actually vectored by hand) which minutely variates the original colours and removes what may well be unnecessary detail. For example the detail stoke just above the model's buttocks. Subtle but very nice. What completes this piece is the use of a light canvas filter which gives it that lovely rough-to-touch cloth appearance and couldn't honestly be appreciated unless seen in full view.
I've not had the pleasure of commenting on your work before friend Dream, but as this is a first I'd like to give you two thumbs up for choice of medium. A shake of the hand for colour preservation and a round of applause for capturing one's imagination. It's an elite work for a reason! I like it! ^__^
