I like the creativity here. You aren't kidding about a shallow DOF. What would it look like if you had the 15 balls in focus and the cue ball out of focus?
At first I wanted to say that it was a little too short...but the more I look at it, the more I like it just the way it is. I really like how the rest of the balls almost blend together. Great job!!
This is pretty cool - nice and simple and makes for a good background. The top of the white ball is a bit overexposed but otherwise everything looks great.
Every day you may make progress. Every step may be fruitful. Yet there will stretch out before you an ever-lengthening, ever-ascending, ever-improving path. You know you will never get to the end of the journey. But this, so far from discouraging, only adds to the joy and glory of the climb. - Churchill
