Nice work, but yeah hard to beat DOTPOTZATGPOSSA! :) Only thing that bothers me is that the ivy just looks scaled up. I'd think ivy that has grown to ~1 metre thick would probably have much denser foliage, the "trunk" of the ivy probably having regular sized ivy growing on it. Just took a look now at DotPotZ and I think that's how he approached it, the big thick trunk that grabs the helicopter looks to be a 'rope' made of thick strands of ivy wrapped around each other, with patches of ivy leaves on it.
