Well, I won't post all 30 paintings of the marathon here, as long as I upload them on http://insgesamtingobert.deviantart.com too. So if you don't want to miss something, be sure to visit my gallery there. :)
I made two versions for day 11. It's acrylic painted in my small moleskine and for the second version I played around a bit with Photoshop. Very simple effect though. If you prefer one version please let me know.
