I think we covered a lot of what I love about this during the EPIC ART BETA, but it bears repeating. The layers of colour you used for your background are sublime, I ADORE how you made the jagged overlaps so reminiscent of candle light AND created the perfect atmosphere with the curls of black seeping in from the sides. Actually, the lighting overall in this is gorgeous, that section of his hair that you made reflect back the fire is what is currently giving me joygasms. <3
The billow in Snapes's cloak adds DRAMA to what would otherwise be a fairly static pose and the painting on his face.. well, it's just lovely now isn't it?
*slow clap*
Bravo, m'dear. And may I toss you a gauntlet of EPIC!Background love? You've clearly proven that you can do eet ;)
