Ok, anatomy rundown and other things...
His legs are very short compared to his arms and the rest of his body.
His cape has a very thick outline to it, and the pink line doesn't match with the rest.
His ear is very very large.
His head is a bit too far back, like he's about to get blown back. His head is also very squat and his right eye is popping out of his head.
Buckles on the middle belt should be placed a little higher.
Weird use of AA on his arm and chest. Try the Capcom method of lightening the line colors first.
