Not bad! What is there is clean and easy to follow. There are a few HTML errors showing up in Opera/Firefox though - you may want to take a look since a great deal of users now use alternate browsers.
Oh, and you may want to consider ditching the very intrusive advert bar down the left side. Most people tolerate adverts if the site they are visiting offers them something they cannot get elsewhere. But since this is a portfolio and you want something from THEM (i.e. their business), you don't want to put anyone off with intrusive advertisements... especially when they advertise your competitors!!!
This certainly looks very crisp and clear-cut. I myself have taken attempts at web design but the pages always look cluttered and untidy, but you've done a fantastic job on the layout of the page. Simple, which is ideal as lots of media distracts from the purpose of the page.
The only fault i can find is, as said before, those advertisements.
I agree get rid of the advert! It kinda spoils the feel of it if u want adverts on your site try the text adverts that google do they aren't as in your face
But yes i like it and it's very original looking which is always a + to me
Simple & clean, i like this sort of site
But the only thing i have to critique is the head cutted on the banner...it's not very beautiful
The rest is fine, good job
