There is a very cute website and it is called "Draw A Happy Fish In a Cleaner Ocean" they have a simple drawing application and you draw and submit your drawings and vote on others drawings. It's not like Queeky where you have your own account and folders with your completed drawings. You only draw fish or ocean related things there. You can't save your work for later use but you can edit your work after you submit it. Go check it out, there is hardly anyone that goes there and they really need more activity there to make the site more fun and have more drawings to vote for:
