Clean up the lines. The color palette is very much like Jamie's. I say take it further and change it up. Avoid using black for shadows. Staging could be better. Staging. Linework. Color. all need to be fix. I rate originality a 2.5 for it being gorillaz and not your own. Technique is rather rushed in my opinion and not finished. really look at their bodies. those hands are awkward. Use reference for the hands and pose, even shoes. Murdoc's hand and arm is awkward. Sketch it out again and rework the final lines, I suggest traditionally. Good job. work harder!
