Awesome. I like the creepiness of the pot, I think it mates well with the spookiness of the exposed roots. A little shallower perhaps would be preferable but it looks cool. A few years out once you get a chance to develop the branching this thing will be great.
With traditional coil wiring you can't bend a trunk this size very far or it would break.
The rafia keeps it from breaking since it supports the entire surface of the trunk. But you have to use it in combination with guy wires.
The bending I've done here isn't that drastic, I've seen examples where people bend it 180° without the trunk breaking (using rafia that is).
