I think it will be better if you change the color scheme. Blue font on black background is hard to read. Also you have some big empty space in the top graphic. Is it ment for a banner spot or something?
The overall site seems good to me, you can better play around with some base color of the site. The content of the site are well organized, you can better do with Google ads.
overall seems nice to me but add 2-3-4 picture with blog to make sure the reader will come back again. oh yeah the color scheme should change. not bad at all.
