Really nice start, and fits in nicely as an icon for an app or 'digital' works. Can we do some variations with the type face? It feels a bit too informal for me, and/or some color options.
What's the idea behind the colon? It might distract me more than add but ....
Can we marry #4 and 22. I like the new "Running" type, maybe use that with for the My TIme as well or something similar. I prefer the original colors. Try some black in there?
