This one falls a little flat with me, unfortunatley. The colours are rich, but it's shot at an angle where your eye isn't drawn to anything in particular. I'm wondering what to look at first. Maybe a different idea (in the future) woudl be to get up really close to something - like a ball or a club or something, and then shoot the same thing but with something in front - just to add interest. Another idea - maybe shoot from an angle from the rounded thing in the center. Think of negative space when you compose shots and sometimes (but not always) a rule of thirds works. Try putting something striking in front of the viewer's eyes - think about where their eye will move when they look at the image (doesn't always work for everything, but in this case it may have done the trick).
