Todays resource!

Today I found a link into site, where is a cool feature. Slider showing animals (or humans if you choose to) and it changes the photo every 30seconds. Croque sketching! Should be great style to improve your overall shapes and learning how to get movement into your creatures.
Here is the link for the site http://artists.pixelovely.com/practice-tools/animal-drawing/
Here is only few I made now, I am planning to do lot more of these in the future...
