Hi and welcome.
Some nice designs, but I'm not really sure what to think. Alot of them seem to be draft designs (lorem ipsum) and not real sites. As I'm sure we all know that the difference between draft designs and working designs can be heaven and earth.
Three of the sites look exactly the same (piczo, profilespin & profilepod) and the only content that changes when clicking on the navigation is below the viewing area (viewing on 1024x768). If I click on top navigation on piczo it links to pages like this:
Animated gifs and all! WTF
auroxservers.com website is not showing any css only straight html.
codemydesign.com looks nice but is just all lorem ipsum.
All in all, you have some nice designs but as far as I can see 90% of them are just draft designs and don't really belong in a portfolio of your best work. In my opinion, a portfolio should contain finished websites that reflect the highest standard of your work and not a sketchpad for designs that didn't make it to finished websites.
That being said, sleightofcards is a slick, simple website and I would like to see your personal blog layout brought to fruition but without the archives dropdown in the header picture.
