Good guess, Veronica.
I don't cycle much at the moment, but I used to and have plans for the future. I was looking for pics on my harddrive when I came across them from 2005.
I'd posted them before I realised that they were a bit different from those that I'd seen here previously, but I'm always surprised at the variety of interpretations and was curious to see what everyone made of them - sometimes abstract works well with even a detailed pic.
I found them quite tough as well and I'm not overly happy with the queue of cyclists one, but your version is great; I love the watercolour look.
