DRAWING THE HUMAN BODY IS HARD ALONG WITH BURN MARKS, yes his whole arm is burnt, Lucifer is an abusive asshole if he is pissed off especially to Levi. Anyways I made like three backgrounds here is the real one

The second one where I tried to ' shade ' MhmhgM 

It's supposed to be Lucifer's blue fire

and the last one

A poorly drawn shadow and this was supposed to be the original one combined with the second one 

I hate all of them
