This is Thanatos! He's the Greek personification of death, so pretty much like the original Grim Reaper. He's the son of the night goddess Nyx and the twin brother of the god of sleep Hypnos. He's a god of death like Hades, but Hades presides over the Underworld and Thanatos is like his right hand man.

Also for the artists reading this, what do you do to get over art block? Because these drawings I've been posting recently are stockpiled from a couple weeks ago, in actuality I haven't drawn anything for a week now ;-; but if you have any tips pls share tysm
