Need some comments about the design, and materials PLEASE!
looks nice. what kind of colormapping are you using?
Exponential
thats what I thought. Like someone said in another of your threads, the exponential is really dragging down the contrast and washing the image some.
design comments
Like the building - looks like the tapered poles holding the roof need something to bear on at the roof connection - a beam or a metal tube, or some splayed brackets to distribute the load - also not sure what material these are - metal, wood? Like mentioned before the image is a too dark - looks like your glass IOR is set kinda high. The combination of materials is nice.
Hi Bernardo, what’s up? i have to say that i agree with percy here, the exponential colour mapping is washing away this image, i think you shoud really stick with linear, its a bit more tricky, but gives nice results, as for contrast and saturation goes, as for the materials, well, i do understand thats a tall building, but i think there should be a way around so you dont get all those repeated tiles over the walls (every one), and as for the design, i think that it looks nice, just a comment about the giant toothpicks holding the superior roof, i think that it should look a lot better with some I beams, (i guess that’s how you call them in english ((vigas I)) and the wood under the ceiling doesn’t fell right to me (but again that’s just me)
Other than that, it will look even better with all the usual props.
Cheers buddy.
I’ll send you a private msg tomorrow.
Honestly speaking, the design doesn’t work well. The architectural elements are somewhat disordered and not related, unitied together in my opionion. The white wall in the middle is ‘lonely’. The window form on the right side has little to do with the whole building, again is ‘lonely’. I recommend to change the roof to be either darker or lighter, so as to be more definitive. This kind of style’s design requires a good intuitive grasp of dynamic composition, I think. 
I’ll have to disagree on the point of exponential;
it does desaturate the image but in my opinion the surface shading & interaction between light and dark is far better than linear. Personally I use exponential then resaturate & contrast in photoshop, best results IMO.
