@Forsoothe, I’m sure I’m the Last Person you want a critique from, but I want to critique this display on several levels, for the benefit of the other forum readers. If you care to benefit from it, too, all the better. If not, your loss.
First off, the display. Tons and tons of repeating elements. Square mat, square stand, square pot, square accent pot square accent jita. It’s just too much straight lines and hard angles.
Accent placement: I can’t really see where the trunk comes from out of the pot (heck, I can’t even see the trunk!), but the apex is over in the left. As is most of the mass of foliage. So, assuming the movement is from right to left, why is the accent on the right? It would be better placed on the left where your eye would move from the base of the trunk (if it could be seen) up to the top if the foliage mass, then follow the curve of the cascade branch down to the accent which stops the eye.
Stand: ive never before seen a pedestal stand used with bonsai in a display. Monkey poles in the garden, yes. As a formal display? I don’t remember ever seeing one before. It’s different, for sure. It’s certainly not “Japanese”. Feels more “Roman”.
The pot looks like a quality pot. I’m not a fan of tall cascade pots. But some are.
The tree. I’ve already mentioned I can’t see the trunk. You say it needs “tweaking”. Yes it does! Tweaks on steroids! It needs “styling”. To me, it looks like a ground cover juniper I can buy at any garden center, pulled out of the black plastic pot, and stuffed straight into that cascade pot. I see no evidence art, style, form, or anything.
I’m just calling it as I see it.
Here’s a cascade I’ve done:
