hey pale, yeah the lighting is the only thing imo, do a black layer on linear dodge and pick that nice green colour that you have there, and just brush with that and box blur it a bit and you no lower the opacity and stuff, you could use it to create some awsome lighting. it still looks grea tho imo. also maybe some levels.
I love the colors and how the render blends so well with the rest of the piece! Great work! Keep it up!
