I like the combination with the kinda rusty, barndoor kinda table. you can imagine an old shed, rusty hinges with an oak tree leaning to the door. All your elements tell a story. I just don't see the link with your kusamo and it's to far away from the tree to be part of that story.
Neverless, this is a beautifull tree, congrat's.
Thanks!
..What Kusamono should fit better in your opinion?
Maybe something that suggest a hedge, a very small Hawtorn maybe. Or a fern, add some hight ? For me it looks to flat.
Another option could be to add something on the big , empty, white space between tree and kusamo.
