Cute!
If you want a good solid boost in views, make the thumbnail view a cleavage shot and change the rating to Teen. I'm GUARANTEEING you you'll get some more. ;)
This is a great pinup by the way! Nice work, especially for your first try. If you're interested in anything constructive to improve on, I'd say the feet and hands are a tad off, and could use more detail, like fingernails, high heels (to add to the classic pinup look), and/or some deeper shading with brighter highlighting to accentuate the curvature of her body.
Just my humble opinion. Don't take anything i suggest too seriously. Just trying to offer some useful criticisms. <3
