I'm in no way an artist, so take with a grain of salt-

I know the aura was probably added last, but it kinda feels exactly like that and is not fully cohesive with the drawing (kind of more like an after thought). It also hides/blocks the hands. As a brighter looking energy aura, maybe the hands should be illuminated by it and not dark/shadowed? Or if its more of a foggy aura with density, then make it more consistent and cover other parts of him as well?

Still worlds better than anything i could do! Auras can definitely be pretty complex, but i think it can also potentially add a lot to your drawing!
