Hey this isnt bad. Its obvious you know your way around a digital palette, so I wont make this comment too long. My only real critque is that you have a lot of confused light sources, which flattens and takes away the atmospheric depth that you could have had. Also with how many glowing dots you had, my attention was completly drawn away from the arm and hand at the bottom; and because its just an arm and a hand, I really don't have much interest as to whats going on down there. Try creating a visual path for your viewers to follow! That way all pieces of your art can work together to create geschult.
