CnC:
~The head looks disconnected from the rest of the body.
~As Tressa said, the elbow is much too curved.
~The segments of the arm are unequal. Measuring from the shoulder to the elbow, and the elbow to the wrist, the length should be roughly equal.
~The chest is really flared out.
~The thighs are really short. Please refer to CnC Point Number 3 (Shoulder=hips, elbow=knee, wrist=ankle).
~The butterflies are unshaded, making them look out of place.
~The thigh also curves in at the knee area too dramatically.
~The shirt's color around the chest area bleeds into the jacket color.
~The background makes the picture look flat due to the blue being only one shade.
~The shading could be blended a little more.
~Shading is accurate 8D
~Love the pose 8D
~The wings are so cutee xD
~The fingers are (MUCH) better than mine.
