Love the one you're with

Sometimes I can go somewhere wonderful to draw, and sometimes, I can't. Today I sat on a busy street, near the corner of Del Amo Ave. and Bellflower Blvd. and drew an orthodontist. It was an interesting building, and as the shop was closed, it had ample parking.

Here's my warm-up sketch. I'm smudging my pen all over the place. I think I only started having that problem after putting in the refill. It looks fines, so I'm thinking I really just need to stop dragging my hand over it.

Thanks for looking.
