man your lighting is all over the place, on the hand its up to the right, on the face and left arm its up to the right, on the body its straight on from the front and not that high... what makes it worst is the background, the white lines look like they have a drop shadow saying the light is up to the left.
all of the highlights are random... highlights should always reflect from a source and each one you have is a different shape pointing to a different direction. meaning you have no cohesion with your reflections. they confuse the image.
the neon in the back makes it worst, you have no edge lights on the character, making it feel like the background and the character are slapped on top of eachother instead of a scene. your shadow color is a solid reddish tone when shadow color is actually the ambiant light in a scene. which i guess is hard to figure out here. because of the abstract nature of it.
the anatomy is a bit off, when the knee is rotated inward that far the foot cant be facing forward... without force..
