I think the slab is too heavy for the tree, and its light colour would dominate the composition. But you’ve probably done it by now and it’s looking good on the slab
Let’s see now that it’s done. You may well be right but I’ll point out that it’s dark and pouring rain and cell phone so, you know pics are only so good. The tree will have a bit more visual weight even a month from now when buds are extended. Anyway I’m glad I went with stone, good practice, all sorts of fun to put together, I’m kinda wet now..
I would have liked a hair forward lean, missed that. It’s the first pot from collection container so next time I could really reduce the rootball more, thinner, smaller. As is now roots are well covered, maybe as it settles in I’ll lower the surface a bit and try for some undulation and interest in that too perfect soil dome.
Anyway, enough excuses, thanks for the input and here it is for now.
