The banner at the top is a little too big, in my opinion. Also, the two ads in the right-most column are too wide to fit into that column.
Images are very cleand and color is very good i like layout all information is really very usefull to everyone
I should opt for a two-column home page. I also would welcome your visitors on the main and put your blog on a blog tab. In wordpress you can do this in settings menu.
