Carnage Mutant Zombie Turtles

one of my past nightmares like this shivers down my spine. I guess drawing one turtle looks just fine... but should I add the other three?




drawn using GIMP 2 program. Outlines and all other stuff are mouse-drawn only. (Ink-tool, airbrush-tool, eraser-tool, smudge-tool etc yadda yadda... non-traditional art sketch)
