Marker Pen on Paper
It is always hard when producing these line drawings to resist the urge to start shading; it seems the natural thing to do, especially when you have recognised a foreground, middle ground and background in the piece. It is also tricky to include all the details at just the right scale for it all to fit in without looking awkward. Whereas you can tweak still lives and landscapes, with a building, if the windows are all different sizes, it will definitely be noticeable. I quite like the result though and it was actually a rather enjoyable process.
