A while ago, I came across a group on facebook called The 52 Week Illustration Challenge.
It's a group of over 2,000 members from all over the world. Each week, a new theme is given and we are left to our own devices to make this piece of art in any form and with any medium that we so choose. It's all about having fun, being creative and doing whatever that inspires you.

Here is my Week 35 - Paris challenge piece. This piece made the cut so Yay!.

I am happy with it. Anyways, there are many more illustrations from other artists around the world and if you are interested in being challenge and want to give your artistic side a go, this could be the place for you. http://illo52weeks.blogspot.com.au/
