Bicycles? Impossible to draw! Two perfect ellipses, fit into a complex triangle shape... and forget the handlebars!
This is a sketch I wanted to use in my bicycle book. A scene of flying over the rooftops and chimneys... into the night. I'm sorry I never got to use it, since it was one scene that sort of motivated the inspiration for the book.
It's fun to look back at all the old sketches that an artist never uses. They're very telling. If I ever get a chance to take my book to schools, I'll enjoy showing the first dummy... which is at least 70% different from the final version.
I'm not sure the final refinement is always the best.
