This is a request from my wife. When I started this drawing I saw shapes and shadow and that is how I am drawing it. I form the objects in the drawing through shading. The key, for me, with this technique is to move rapidly through the drawing changing my pencils just as fast. I put a light tone in and follow it up with a darker one. Precision is only relevant to the general location of objects in the photo and if they fall elsewhere I just work it in somehow.
I like using this style as it gives me freedom from lines which I sort of hate. Not entirely but I try to use them as little as possible. And that being said, all that's missing from this drawing is a row of buildings which I will texturize, for lack of better word, by means of a similar technique. I should be using some projection lines but I'm not. In the end I may or may not scan the drawing for areas that I feel need more emphasis and detail them up (with lines). So lines inevitably may find a place in this drawing after all. Little bastards.
