I've been having so much fun with the daily art challenge I've been participating in—"The Month of Love". It's such an inspiring group of illustrators, and each day truly is a fun challenge to post something new. Some days are open to any love-themed imagery, others days have a challenge topic that everyone has to create from.
I find some days allow time to really develop an idea and a more finished piece of art, but most days are more of a conceptual exercise that allows for experimentation with sketch process. It's been a great experience so far, and we're only one week in! With 20 new pieces of art posted each day, be sure to check it out and visit often! monthoflove.blogspot.com
Here's a few pieces, including the blog header, that I've contributed so far:
