First drawing

Today I came across something hidden in my folders and completely forgotten about. It is my first ever attempt in drawing a shoe. Yes, this is my first ever drawing and what a long way I have come in honing my drawing skills. I wouldn't say my drawing is worth framing up in a museum or something, but it is good enough at this point to enable my factory to understand and build the shoe up. This drawing above is purely self indulgent, a shoe with diamante string t-bar is just asking for trouble, no one would be able to walk in it - too delicate. What was I thinking?
