The blending on the yellows is great. I like how you spotted the red areas, but there's places were the red looks a bit sloppy. His claws looks good as well. But I think this wings and blades need more. Perhaps the blades could use some freehand as well. But I think the wings really needs more work. They look too bland. Maybe some harsh highlights? And his eye could be blended more smoothly like the yellows. But overall, great stuff!
