My work method is to deal with several instances, first I present a moodboard to define the aesthetics and general elements, then I propose the distribution and functionality and if everything is approved, I do the modeling and rendering to have a correct visualization of the changes to make.For project reasons, I allow 4 corrections, one of them after the moodboard instance, two after the distribution and functionality instance and only 1 in the modeling and rendering instance.Delivery time and price will depend exclusively on the project to be carried out. The base renders to be delivered are 6. If you add more, it will have an extra value, just like if you want the original file.
