I really like the color
The color was really nice work here but it's also all the energy that you put fourth into each item and prop to make it all come together and the color adds to it adding some sparkle to different points to this like a bottle or aliens eyes would have a nice ending effect here and I suggest these as ideas only for you to decide what's best anyways nice art piece
