Robo, I'm not sure what level of comments and views you're expecting but it seems to me you're above average on those figures. I agree about the thumbnails - they're not eyecatching enough to stand out. They're mostly close-ups of fairly expressionless girls or bodyparts, which doesn't give the casual browser much of a clue about what's inside. Might help to have more evocative titles, too. Thumbnail and title are the only things that will get someone to click on your images, until they learn to recognise your name.
