to be honest, i know i'm not good artist but i think something is bad with light from CM and left back hoof , because if cm is under the wing then why light is on wing ? and this same thing about tail. but of course this may be your vision and your style, so for me this is really good drawing
The intention was that it's a glare on the "camera lens." Like when you're driving and the headlights from oncoming traffic cast a glow of light that goes beyond the edge of the window in your vision. It's similar to a Bloom effect.
