Spot on! Now that I look at it at a user-friendly point of view, and not as a "user-experience" point of view, the site does look rather spaced out.
I tried to keep at least 50 pixels of white space between major sections, such as the navigation bar. I noticed, with my new "point of view", that maybe I can tune the "margin-bottom: 50px;" part down to maybe a "margin-bottom: 30px;" or something in that vicinity.
I've been told on another forum that a lot of the gradients and shadows are too blatant, and I will for sure tone those down a bit. I've also been told that it looks rather "appley", but I was designing the website with that in mind.
I realized that I've uploaded an old version of the site, and the home tab (under the navigation bar) now reads "wadio". I changed it a few weeks ago after I got confused as to why I put "home" there, instead of something else. Thanks for reminding me

.
As for the curved boxes, it's an interesting way to put things. I immediately thought of "Babies-R-Us" for some reason (don't ask why). I think I'll keep it, but as you said, everything was spaced out, so maybe with some whitespace reduction, maybe you can see those in a different light.
I'll upload a new image with any changes I can do as soon as I can compile a list of changes that I can make.
Thanks for the feedback Wyzo. I really appreciate it, it's been a great help.
