On my big monitor it looks fine, on my laptop monitor it's below the fold. If the ads appeared directly below the article rather than further down, you're likely to get more clicks. Also, Google allows you to have up to 3 ad groups per page, you may want to consider adding additional ads - possibly an adsense image ad to spice up the look of the site.

Hmm... too plain to me... well if you have that less of content, I'd recommend you to use CTR theme. =) It's mainly for those who want to monetize their site =)

Too many white spaces, im using my netbook.

Text is to wide so basicly looks quite empty (page is).
Then after changing layout i would ad another add block between title and text (i would use 728x90)
