How is my site looking/have I missed anything obvious?

So I'm going down the route of a few micro-niche sites hopefully and this is the first one i've managed to produce, took around a day, all design/code/content produced by me.

Have I missed anything out that will hinder me greatly or can anyone give me a few pointers to get into the game?

Thanks,
Chris.

 

Nice landing pages, USE some SEO like relevant h1 tag, external linking.

 

I submitted to a few directories and search engines and commented on a few blogs, anything else I can do?

looks great. Just build links now.

 

You have one big adsense banner at the top instead of your own header.
the design is good, but let the visitor remember the name is essential. So change your header put a logo and description there.
