Project 2: Fantasy Sport Test 1

This image below is a quick test of me putting the different 2D images I have produced to produce a 3D world. I decided to go for a futuristic neon glow for my idea 'Hovering Tennis' played within a bubble in space. This image is to give you a sense of what my idea is, however I have a long way to go before this will be complete... I have to add crowds, tennis rackets, balls, hover boards, referee, planets and the bubble before I can even animate so I best get cracking... feedback please?
