A close friend of mine (someone I know personally for many years) is amazing at making hand sketches and also loves videogames. He's an architect/urban planner like me but he loves drawing and he's trying to make a living out of his passion for hand drawings and sketches.
Right now he's doing something very interesting. He's actually making A3-sized posters from cities and locations from popular videogames, all hand drawn by himself with just digital finish. Take a look at his work:

Here's more of his work:

He's currently working on a website where you'll be able to order printed copies of those posters. It should be done soon.
Please take a look and let me know what you think
