The job is clear. We want a map illustration with a false perspective. This is, we indicate which will be direction in which the elements would be projected.
We want an illustration in which some details will be illustrated with rigourisity and some other elements which can be handcrafted. We will provide a real map, some photos of the place and an example of the type of maps we are looking for.
I am posting an example of what kind of illustration we are looking for.
