Technique Challenge: blurred movement

I'm struggling today, having saved my least likely to succeed photos until the end of the week. I have to save my BW because I might be doing a portrait shoot on Friday.
In this rather cruddy photo, I sat on the ground and surreptitiously (who am I kidding?) took photos of people walking past me. I had so many shots of what appeared to be one leg that I layered a few together. This was not my plan at all, rather a last-minute cobble because I couldn't get any good street shots and I really don't want to go back outside with my tripod to do light trails.
Busy few days ahead of me and I'm away at the weekend (and wondering how I might fit 2 new baby shoots into next week's categories) but I will get round to looking at journals at some stage.
