Hey Blu,
I like the new site it suits the topic and I think you have done a great job of compacting the good information on the previous website.
I would reccomend getting a full domain, what host are you on may I ask?
All you need to know is implement the new design into the old pages. You need to keep all your pages consistent.
The one thing I would say on the design side of things is the contrast between the bright green background and the white content background is very heavy, so why not try blending it a little bit by adding a bit of blur to it.
I would hide your email adress in a mailto: tag so for example switch it for.

To avoid spam bots getting your email this idea isn't foolproof as spam bots or spammers will look in the source and find it, but unless you are not having it encrypted, it is usually safe. Just saves you deleting 101 spam emails in your inbox so you can concentrate on the people who really want to speak with you.
All in All I really like your site and I wish you all the best with it.
