Thanks for the tips. Here are the missing images I wanted to share with Okh regarding the container texture issue. As one can see, doors still work in progress :) I took some pictures of real ones then tried to resize in order to fit the drawing. Coloring is also to be worked on.
Now I have to draw this complicated multiple slopes roof covered with solar panels and funnelling rain water into the central tube seen on the first floor image. This big tube is linked to an underground mini hydro-turbine to produce electricity, before getting to another underground water storage.
This “technical” bio-farm project is to be located in an equatorial area of the Globe (I can't reveal the exact location for now) and must work totally off-grid, meaning generate all its energy needs. The present building is just the “administrative" unit.
Many tanks again for all your help.
