Hey ChrisHPZ,
First off, like others have said, very cool splash page. It's a strong background image and the subtle cloud animations are a great touch. I noticed that the loop of the clouds isn't continuous as they suddenly disappear and then reappear. One thought would be to have the clouds initially fade in and then fade out as they move off into the background. That way you'll have a smooth transition from the end of the loop to the beginning.
Your work portfolio site is very clean and easy to navigate. I also checked some of the other sites you've made and like your use of strong colors. I have a few suggestions that might help enhance the look you are going for. While a compartmentalized layout can work well depending on the setting, I've found that the most visually impressive designs tend to have at least some integrated visuals. For example, the header, banner, content, side bars can be weaved together with different effects and not kept completely separated in the design. Simply put...If you make your layouts less "boxy", your designs will appear more seamless.
Framing the website with a subtle background image can help structure your site and also add some visual flare. A very simple example of this can be seen with Gamespot.com where they use a gray banner on top that encompasses the header and navigation. Of course, there are many more creative ideas for backgrounds but this is just a simple example. They also use a dropshadow that runs vertically down the edges of the site to add a more 3-D feel.
Generally, I've found that the more a site pops with the effective and balanced use of shadows, gradients, glows, the more it grabs a user's attention. All of these techniques when used properly, keep a site from looking flat.
In the end, your portfolio site is a great start. Making it more attention grabbing will help you get you noticed and ultimately, hired
Hope this help,
