Sweet, I love how you've mirrored the rough attitude of the characters by the posing, and jagged strokes. How you've balanced the accessible with the girl in the front and the dominating charcaters partially obscured in the back.
I don't think it needs more medieval look to it... this is top-notch for what it is. I've actually taken to looking into using cyborgs for my own setting, but instead of being 'better hackers', they're really just replacement limbs and eyeballs for when people are injured severely. Which leads to a disassociation with the rest of society, since in the setting cyborgs are seen as the downtrodden or poor who aren't capable of having the insurance coverage to get a limb or organ cloned. Which is where the origination of the Symbiont Confederation results.
beautiful! always amazes me how some artists manage to make highly detailed art with such simplicity, so impressive! Love the color scheme and contrasts with the bright green, in other words I love it, so very very much!
