The first thing I notice is the 12-13 cluster without an obviously easy solution. The 15 ball can be made first shot to draw into them but it's not the easiest shot and may not open the cluster with a good option as the middle pockets and lower right corner are pretty well blocked. Not to mention the 11 ball looks to be barely on into the top middle.
For spots I have an easy 4 ball. 1 and 2 are not on to their nearest pocket directly so need some thought, but the 3 is the main focus I think. It could be used as a last to 8-ball option but that could be problematic with the 11,12 and 13 where they are.
So my choice would be 4 to 3, to get rid of the 3. If I come up short, fearing hooking myself behind the 13, I can draw off the side rail also for the 5. If that position is not good, or the shot off the 5 is not good, I have options with the 2 and 6 balls.
If I get out of line, I'll probably try to get rid of the 1 earlier and use the 7 as my last to 8 option. If things go to plan, 1 is my penultimate ball. The 12,13 act as a bit of a stopper for the 1, but if I'm short I got a clear path up and back off the end rail and if I go long the 1 is on in the top left corner, so I'm likely to get a pretty good shot on it.
From the 6 to 7, if I get a bit straight I can go 2 rails with inside aksi to get on the 1. If I'm short I can just cut it 1 rail. Straight on it would be a big problem.
So here's the pattern that comes to my mind. Feel free to critique,
