I love E Nomine, and Mondengel is one of my favorite songs by them (it's like in my top 5 by E Nomine, seriously). I can see how it inspired a work like this, listening to the song and looking over all the details of the image I can sort of see things that weren't there in my head when I was just looking at it with silence around me.
Nice job with the circle too, one side's a bit red and the other a little cyan just around the edges so if you look at the circle without realizing that color is there it just seems so odd. And how the colors are different above his head but the right side just kind of blurs into the left. This entire picture is a delight to look at, I feel like I should just put Mondengel on a loop in my iTunes and stare until my eyes start to hurt
