That, sir, is looking fantastic!!
Regarding the aerial root..
Hmm... The idea is great!.. if the trunk where SHAPED differently (Even with scars/bumps in different locations), I believe it would better accommodate this design idea (As is)...
For me.. the light/shadow from the obvious draping onto the trunk is slightly distracting.. ONLY because the fact that AFTER this section.. it “appears” to be tight-to the trunk and straight down. In my opinion: I like the root, The idea is SOLID.. it looks great.. but I would, personally play around with the placement/angle/droop of the root.. try to find something EVEN MORE ocularly pleasing.
