Seems pretty good to me! You seem to have placed the spear as it was placed, according to these coins:
I would just hang the sword higher up, and on the left side (as should be for right-handed people), to reproduce what's seen in the coins (maybe I'd also go for another kind of armour, but it seems @wowgetoffyourcellphone chose scale armour for some units, I wonder if for some reason):
I'm quite confused about the helmet. You used a Chalcidian, while I'm not sure if the coins show a Boeotian, which would be highly irregular since the equipment placed in a trophy should be that of the defeated army, but on the other hand this is a highly irregular monument since, unlike all previous trophies, it was made to last, so I wonder if a decision was taken of using Theban equipment instead (which would require another shield device). I couldn't find any commentary on this for now, so I cannot say for sure what's going on with this (it could just be a Chalcidian or Corinthian tipped upward, but doesn't seem so on the right coin).
We chatted a bit with @vladislavbelov when we met. But the main issue is too many unit /object variation and the fact not all users support instancing.
