nice attemp and good concept, but try not to do monotone if anything do B&W if u cant work out coloration, but monotone is unapealing, i suggest u download green tunics fractal packs from DA, i dont have the link onhand, but they are great and will help you evolve your effects, also try adding gradiant maps, and textures just to add more depth and feel into your tags.
on the plus side good lighting, and positioning.
