Hi Greg...
I might usually take exception to the concept of clearly and sharply cutting off the border of adjoining artwork but here, it is this very same thing that seems to work so well for you! The pool table is Magnificently defined but might have found help in being spotted IF there were at least one pocket visible. It was wise, as you did, to drop the bottom border of the tile above into the field of your own art. The lower border didn't give you too much latitude and the border at the right was superb, as you joined it and kept it visually sound. You can be proud of this tile because to me, it seems to show that you met the challenge masterfully! Sleep well in the knowlege that you're doing your part! Best regards to you Greg, Eddie M.
