I have a new website that I love, http://www.ratemydrawings.com. Rate My Drawings is an online drawing contest where you draw by using your mouse to create an illustration or drawing on the website. Then, other artists take a look at your drawings and rate them.
The best part is that you can get the little art program to "replay" your drawing, so you can see the strokes you made step-by-step and you can place your drawings on your own website or blog for others to watch the animation of you drawing stroke-by-stroke.
They encourage work for holidays all year round. I like to look at other's work for inspiration.
The only drawing I've done so far is here: http://www.ratemydrawings.com/drawings/halloween/14892.html.
