I'm not a character modeler, so I'll leave the critique of the actual art to other people. Your site in general looks nice, but the functionality is just much more complicated than it needs to be. All you really need is three large thumbnails on your first page that then link to another page with more detailed images of the characters and props. Another benefit to this would be that all your work will be immediately visible. As of now, the first thing I see is Maalik. I actually like the Dr. Yanovski model more though, and there's always an outside chance the hr/recruiter/art director won't click through and get to that. They might just judge you on the first thing they see, and decide it's not what they are looking for.
I don't know a ton about web stuff, but in general I would advise to stay away from anything flash or lightbox. You will find people who are ok with flash and lightbox, but you will also find an equal or greater amount of people that really hate them. In my opinion, it's not worth missing a job opportunity because of lightbox/flash.

Anyways, your work is pretty cool, good luck!
