Hey Donna, I would look into articles about tags, you're using the right words, but they are more effective if you combine them, like if your painting has a blue background, the tag "blue" brings up SO MANY things, it's hard to sift through, where you could say blue painting, blue drawing, etc.
By grouping your words accordingly your tags will become more specific, and in essence you'll get more tags to use.
Also, I think your Facebook page link doesn't work because perhaps you did a copy paste when logged into your page? you should have a regular url like Facebook.com/whateveryoutitledyourfacebookpage.
