The game is not currently out but the crew have released in sights into the development of the game, here is a production insight video.
In this short video we get to see the ideas they have developed for how they are building up the city, using the first game which had all these gritty buildings that needed repairs to new building that had a future realism. The level design is so complex, I'd love to learn how they develop the 3D space and how they make these textures that look really realistic. I hope to explore this area of 3D and learn how its all done.
as for the drawing mentioned in the title, here is a WIP which i hope to complete before the game is released.

I want to create my landscape drawings such as the above, creating old/futuristic buildings used for my animations. and expand my knowledge on creating 3D spaces to save time drawing each individual buildings, using 3D programs such as Maya or google Sketchup.
