Work on your blending, effects, depth, lighting, color, and over all execution more. The render seems sort of pasted in. The effects are all over the place and don't compliment the render much. Your render is really bright compared to that dark background. Too much contrast with that and also doesn't make much sense. The colors are boring and monotonic. They also don't go well together. Your execution is like, non-existent Everything seems randomly placed.
