I like that you got it down to a single trunk.
It is a bit ''busy'', too many thick branch stubs in one little zone. Sometime, either now or in the next year or two, I would simplify to no more than 2 or 3 branches off the main trunk, all further or future branches will come from those remaining 2 or 3 branches. Which ones to keep?, I could not tell you from the one photo. You will have to choose, but the trunk to main branches region needs to be simplified. Either now, or at some point in the future.
All in all a nice find, and Waka Ebisu is a really nice, dependable Satsuki hybrid.
