Feywild Terrain?

With my D&D group in the midst of a series of games in the Feywild I have been trying to create some terrain set pieces from the terrain I already have. Mrs Daxio is coming to the end of her tether as regards how many hills, forests and buildings we have in the house.

Here I was trying to create a large tree type structure, perhaps a bit Pandora like or Lothlorien ish. 

I am not convinced, not that it might be useful, but that it might be unsafe really. Think that the lower "trunks" I created are just not large enough to support the upper sections how I would like. I recon one moment of excited movement and the whole lot could come tumbling down.

The boards that sit on top of the trunks are also a bit straight edged and don't quite work for me.

I think I will make some broader trunks and perhaps try to disguise the board edges, lichen maybe?

But if I can't do it easily I think I may forget the whole idea. Probably would only use it on one occasion anyway. 

But if it works I could see myself using a set up like this to hopefully excite my players.

Its always difficult if you don't want to start creating new pieces of terrain, sometimes the result is a hotch-potch of poorly put together disparate parts. We will see!
