Challenge 2: Linda's drawing

Over the last few months I've been drawing on a fairly regular basis in an effort to improve my drawing skills and tackle subjects that I would have previously ignored completely. So this challenge wasn't as difficult for me as for some of the others in the group.

However, I've been drawing with pen, not pencil, using cross-hatching etc to show tone and shadow. Also I am not, and have never been, good at complex subjects, perspective and proportions. So for this challenge I decided to push myself. After a suggestion from someone on the group (thank you!) I chose to draw my theme, my back yard, from an upstairs window. This is the result. The tones are fairly accurate, but some of the proportions are still not right, despite my attempts to correct them. However, overall I'm pleased with the drawing and enjoyed working in HB pencil - may do more :)
