How is golf a team sport? Other than that, the sky is blown out and a tighter crop on the bottom would have helped (just below the near-white object -- apple core?).
The detail in the green is good... but it also takes away from the shot. The green needs more saturation... seems like you were shooting into the sun, which took away the colors.
This looks very pixelated - and slightly out of focus (just slightly). The colour saturation looks almost like you're using a really low MP camera or a cell phone camera - but it may have been when you resized the image. Sometimes those resizing programs can do too much compression. Depending on your budget, you may want to upgrade. Good idea for this challenge though and I can tell you took some time to think about composition. Would have been even better if taken at sunset or sunrise - the lighting is a tiny bit harsh.
