It's too plain... Try to insert some images. Ads placement is good. And something about SEO put "more pages" links in all of your site's pages. Good luck and welcome at DP.
I agree- desperately needs images. Maybe you should run a wordpress blog there- you could download a nice theme and it would look great.
you have good colours for your adsense but if you insert one more adsense ads inside your article ,it may give you better results
