It's clear, that you put much work into the tattoos, with how detailed they are. Especially the one at her mouth and the way it's opened add a lot to the dark feeling. I also really like how you did her hair and her eyes and the way her fur is more flesh-coloured than pink, since it suits the tone of the picture. I would recommend you to leave the lightrays(?) out though or make one lightbeam, that's better visible instead. Anyways, altogether it's a fantastic piece, though I have to wonder, what those tattoos are meant to be/do.
Damn, this is awesome. I just looked at your gallery and recognized you're the artist that does all the crazy-ass designs that I admire, esp. the Pinkie Pie stained-glass looking one. It's no wonder this caught my eye so quickly. I couldn't even imagine how you make designs like these, nice job again!
