Right branch gives balance and stability to the tree. Many people like that sense of balance.
Removing that branch will give dynamic tension and a completely different feel to the whole tree. I think the powerful uro and shari in that area attract enough attention without needing foliage there as well.
Either way you will have a nice bonsai plum.
...thanks for the virt , @Atom#28 nice job....
...you can see what @Shibui is getting at with the above image....orientation of the branch in question doesn't seem to jibe with most of your other branching...
...nice tree, be glad to have with/without the branch!!!!!
