its decent. but it still needs alot of work, very good for your first, and i <3 web 2.0.
Right now if you like it the way it is your going to have to come up with some ideas that will take up alot of that blank space on the right side to balance out the design. Either that or move all of the content to the middle of the site.
another thing with the site is that its pretty boring, everything is just rectangular. thats ok for your first site but you want going to want to try and spice things up, but still keep your site balanced and make sure it has good flow.
