Did you actually do something to promote it other than announce it here? Also the content seems a little "different" from each other... Is this unique?
You need to try blending your ads in with your content and theme. The banner you have at the top is especially glaring, and should be placed within the contents of your blog rather than as a banner.
At the moment your site alexa rank is somewhat above 220 laukhs which means your blog has very low traffic, so write good content, promote your content, and build high traffic, then your earnings will increase automatically... there is no any way to increase earnings without traffic...
i think the layout is a bit random, try to tone it down make it more uniform, write good unique content and go for a niche is it will help to serve more targeted ads.
