Hi,
Thanks. One thing I've noticed since I set the site up is that I'm getting more choosy about which ones I put on the site. When I look back at the first ones, there are some that I wouldn't put on there now because I don't consider them good or interesting enough. I guess that means I might be making some progress!
I had a brief look at your site last week and have just had a closer look. Seems a pleasant and easy to navigate site with a good domain name. I expected a little more nature, though the title doesn't have to mean it's nature/wildlife orientated, just photos of a digital nature.
Like the idea of a page devoted to amazon book sales... I scrapped my amazon ads as they didn't make anything when scattered around the site but it may be worth trying again in your style.
