I forgot to take the camera to work, so this was the only arch shape I could find this evening :) A few days ago someone looked through one of the Playschool windows - here's the arched window :) (Overprocessed in picmonkey.com - thanks to @murnane for the suggestion!)
Had a long day today, followed by a long evening, and getting ready for my last actual day in my current job tomorrow - so many things to do!
It's a perfectly fine arch- and the shot works for the challenge. Sometimes long days will do that to you, so don't feel bad! I've been running a few ideas through my head but don't know which one will end up on the screen! How about that!? I'm challenged by a challenge I designed!!
