thanks for the comments guys! here's an update: I sculpted some feathers on the wings and baked everything again, also painted some highlights on the diffuse, they're pretty subtle... and the base got some tweaking too, mostly contrast. I also added another light in the viewport. I think this thing is almost finished...…
not too shabby. I think you should toy with your saturation a bit, though. Either drop the saturation or darken the diffuse, maybe a bit of both. The wings also look a little "nubby". Where they connect to the body it should be a bit thinner. I know it's a little late in the game at this point, but you might consider…
