A new challenge for 100 days? On top of my 365 creativity challenge but with a narrower focus. And the 30 days of blogging. Sure, why not? But only if I can roll it into my main challenge.
1) self portraits - 100 of them in a row, ouch! Not medium specific. Challenging to keep it interesting and not get terribly sick of myself.
2) drawing - probably too broad of a theme
3) painting - same problem as above
4) daily floral - another good option. Good chance to practice florals.
5) daily portrait - like #1 but with more flexibility.
