Please review my newest micro niche site, the link can be found in the signature. I'm actually thinking about selling it.
There is a little too much green on the page, I think it would look great if you made the left column with the adsense ads a different color, and I think you should add some graphics to the page.
I personally am not crazy about sites that do nothing but adsense. With so much media out there, including podcasts, videos, books, click bank products, and more, I think you could do more with the subject to inform your readers. Right now, it's just enough content to generate related ads through adsense, but offers nothing to entice readers to subscribe or return. If MFA is your goal, then you hit it spot on. JMO of course.
I would match the google ad link colors with the colors or the site links. Black usually doesn't read as clickable text. Also I think you should experiment with other shades of green for your title. Or try white, it may stand out more than the green.
Nice pictures, but on the Paludarium Maintenance, Anubias Aquatic Plant and Paludarium Animals there are some problems with special characters.
