I like it and, as a hs head coach, i would love it. My only suggestions are:
1) slide the coach more to the top left corner ... I love the image of him listening/coaching. I just feel that the player's head is being blended with the backboard and takes away from a great point of the work.
2) The play on the far left. Any away you could not over lap as much, maybe slide it down and right a bit.
3) If they had a good record, maybe add that.
4) in the bottom right, a silhouette or faded shot of a time-out or pregame huddle.
I am sure coach loves getting these and they must mean a lot to him. I know I love gifts like these.
