This is a good idea, but the lighting is extremely harsh. It's well composed. maybe next time you shoot outdoors, try dusk or dawn for better lighting.
This is a very busy looking macro because of the grass poking through the racquet netting. The overhead lighting is very flat, washing out a lot of the detail and color. The hot spot running along the edge of the racquet detracts. The red, white and blue scheme would have worked better without the green grass. You should have eliminated the other racquet that appears at the corner of the frame. It does not add to the idea but is distracting to the eye.
