From My Sketchbook

Lately I have been studying a Richard Taylor book about drawing buildings.Posted above is a page from my sketchbook.Drawing buildings is so different from drawing people.More lines, more angles, almost no curves.Especially when you are not using any ruler!But its interesting, and I am going to work some more on it; to achieve correct perspective and straighter lines.
