As a Artist, I grade this a C. If you want to learn to hone you skills. (A) Carry a Sketch Pad & Pencil Look around where you are & Draw, Draw, Draw. (B) Pick several Artists that you like & know how to draw whether they be Western Or Eastern Illustrators. (C) Go on line & search Pencil Art for whether it be Jim Lee, Jae Lee & Alex Ross, look for lots of stuff with buildings. (D) Get a tracing pad lay it over the penciled buildings, Now take a ruler and trace all the building lines and pretty soon you'll start under standing perspective. But there is a lot of work that goes into your trade there are no easy short cuts.
