You seem very engaged in your website. As such, I think you need to start from scratch, not just tweak a little here and a little there.
To be honest, I don't think you have a solid ground to stand on. The site lacks structure and hierarchy, it's not clear what it's about, there are way too much ads and it all just looks very very cluttered. The images are scaled so that they have become blurry and showing compression artifacts. You have a "Pin it" function by each image it seems. It's not exactly a site about beauty or where you try to create aesthetically pleasing images, so I don't see why it would be so likely for anyone to add the images to Pinterest.
Look at a few sites that have won prices or drawn a lot of attention, and see what's good about them. I find a lot of inspiration from Google searches like "Great looking websites of 2011". For example:
http://blog.triphp.com/design/top-15-best-looking-websites-of-2011.html
Start with creating good content, then a good design, THEN you can put some ads in there. At the moment, it just seems like a cheap way to try and make some extra cash.
Sorry to be rash, but considering the number of "what do you think"-requests you've made it just seems like you want traffic to make a few more cents off the ads. If you're serious about the blog, do some serious changes.
