I just got a new CD today, Black Veil Brides, and there is a song called Wretched and Devine. Your picture suits the song perfectly. The lyrics: "I'm the chosen, wretched and devine, I am the unspoken, the one they left behind ... fearless fight until we die, the fallen, the wretched and devine..." Great work btw.
I use regular brushes along with painterly brushes I create. A really useful tool is slight texture overlays (though I don't use them with high opacity), and the sharpen tool. Sharpen just a tad and it will make your brush strokes pop a little.
