How long I don't post here, need to move on.
@Theuns: Thank you very much! Those mountains are made of a cylinder which I modeled with several edge loops, moving each edge to make things aleatory. I'll make the ropes of the house thinner but not so much. Really cool knots Theuns! I would use the 214...
@Tommy: Thank you too! Yeah I think that my sub-conscious have though this way because the rich houses that I haven't designed yet but are in the first conceptual drawing (really small) looks like a banana.

The window is more to illumination and to see the city above. I'll do the inside house but will make as a separately scene.
@Saul: Thanks, I felt it a little to, but I don't know I could do it better and I think that the overall look would not change too much. I think that the spidery in those strings are the crossed lines.
@Patti: Thanks, of course I wouldn't get offended, criticism is always welcome and attended! As I said before, I altered the rope diameter and also said that don't know how to make the 3D looks like the 2D, so if people can they should say to me how.
@Theuns: hmmm....

Will test, but don't wait much from it. Thanks!

Let's see what I've done lately
1,5 Months of of work = Almost Nothing
''That thing'' which holds the city (drawing in the first page) is 3D now, here is:
Ropes now, makes the basic form.

- Some parts are a little crooked. I'll fix
''Streets'' of the city, they have three sizes: Express are large and big, made with trunks, connect big distances; Medium are medium

made with boards and are around important buildings and constructions to connect them to the Express; Thin are really thin

and dangerous because you could fall made with small board and are localized around houses and far areas.

- It's just a composition that doesn't makes part of the city. I did to show all kind of street (We stand on the medium which are connected to the thin that is with the express.
That should be smoke but looks like a sloppy waterfall. I NEED TO DOMAIN SMOKE =(
But then come up problems. Everything is HD so the scene will be really big (in my calculus 300 mega)

and then I tS don't render for some reason, also the tS gets really slow. I think that I'll need to abandon the HD Vertex
