Post the direct URL where your drawing, doodle, artwork is posted (e.g. your blog post, Flickr, etc) in the comments area of this post. This practice will keep all the artwork together. If I find art or pictures by other artists on this topic, I may post them in the comments as well.

There is more information on the recently updated Creative Prompt Page.
