I think they look like a sprinter's legs. Looks like you have some power!
I used to walk 4 miles every day, and my legs still didn't have any definition. Now my legs have a nice groove down the sides. I like what cycling has done for them. Seeing that groove develop was a early great motivator for getting me on the bike. Now it's second nature, and I need to ride or I go nuts, but before that happened, it was all about that groove.
