Overall the design is very clean and it's certainly easy on the eyes. A few things:
The starburst background is a little "OS X" I do like the effect and it is super clean, it's just very popular at the moment... so as far as being original I think it loses a few points there. It is a look. I like the 3rd version the most
I'm not sure I get the logo? Is that an RT? It's hard to see an NT in there, and the logo takes command of the page not your name. In terms of memorability I'd think you would want people to remember your name on your personal marketing site, not necessarily your logo. I like screen 2 for this a lot. No logo, just your name. Clean & simple.
Overall good work.

Thank you for your comments Stuart, much appreciated. I agree on losing originality, but somewhere down the line I wanted to be able to display my jack of all trade services and thus retain a clean/neutral theme, yet still professional as I'm trying to go for the small businesses. Thank you for the comment re logo too...
Cheers
Noel
