very well done homik, I suppose doors and windows might be the next step before you add skin.
Though you need a way for people to get to the top house,
perhaps a fork in the spiral walk way, one that leads up to the second house? Im not sure, hmmm, do some tinkering with it, great work none the less, its really coming along.
Or better yet, a rope ladder...
er here is a rough idea of what i mean, because you'll need a way to get to the second building in the tree... And doors and windows would be much better if their actual objects instead of just skinned on like they are in ps now.
You could try just a door way though, instead of a actual door.
