I see some spacing/framing issues. I would like to see your item description framed with your contact information. I would also like to see a more balanced use of white space. You use a lot below your item pictures but less in between the item description and your contact information and navigation.
Your navigation doesn't seem to cater much to the user. Imo it's questionable whether or not the nav is placed in a good position, anybody who wants to get in and get out could be frustrated with it, though it could also benefit you because their eyes have to scan through the portfolio item to get to the navigation.
Using the title "misc" seems unprofessional to me. If somebody is on your site to hire you I feel like every section should have a purpose. I would like to see a bio section where an employer could learn more about you on a personal level if they so desired.
The audio player could be hard to find if somebody wanted to mute it immediately, I would position it up top. I find that if I want the audio off I want it off immediately and its my first priority on a site, you could leave the audio player down there if you started it on low volume or muted.
Take all this as you wish, as you know design is very subjective at times. One designer loves what another may hate. Oh, I don't see any issues on this page but if you want a print/web job make sure you pay attention to title kerning, don't need to be able to drive a bus between letters
