I need a graphic design - 1 picture, very similar to the one attached. It needs to contain the same elements and approximately the same style as the image below - with only minor changes (e.g. coloring or sizes and shapes of buildings).
In order to be considered, please answer the following:
a) How long do you think it will approximately take to create an image like this?
b) What is your method (software used, etc.)
I will provide more exact details on what I need, but for now consider that you need to recreate the image below with minor modification (e.g. recoloring, new text description, etc.)
