I submitted this piece to a group called "Glorious Red Ripper" which is all about Grell being bloody and terrifying. It does not allow cutesy art of Grell, so if you like him better as a terrifying, murdering, psychopath, you should definitely go check it out!
Also... I FREAKING LOVE THIS!!! You did an awesome job!!! The bright areas of his face contrast so nicely with the dark background, but there's still enough information to tell you what it is. Absolutely gorgeous.
