I really like it! It's technically well executed and the colors are consistent and cohesive throughout the piece. I can really feel the mood. And the lighting effects, top notch. There's always room for improvement though. Stylistically it's not my cup of tea, not doesn't matter it's your art, but I feel like there is a disconnect between the setting and the focal point of the piece. I think that you have a lot of skill but you could work on your skin textures and colors.
I want to mention that anything I say might be totally dumb to you but if you love your art keep doing what you're doing. It could be that I just don't understand the piece or what was intentional.
