Hi Reina,
Your link didn't work for a couple of reasons. Here it is.

I like the look of your blog. It's fresh and clean.
I'm not an Adsense guru by any means, but most people
would ad Adsense to the top or bottom of each entry and in the sidebar.
Ads that blend into your color scheme so they look like part of you content
I hear convert the best.
