Anybody can do a design like that. If it is made by a professional web designer it must have at least some effects. It is too simple and the elements are wrong placed. Try to work on this design for a week, and a good start would be looking at other designer's work.
In the menu, when you are over the text the arrow should become coloured too. And usually home is the first link.
Copyright must be at the bottom of the page content, not in the menu.
The arrows from the menu should have a bigger distance between them.
The title is always portfolio ... etc. The title rule is that first goes BAS design studio then Portfolio. And not all the pages are about portfolio, right?
The last thing is that you don't need images of 1px/1px with such big with and height. For example blank.gif is 1px/1px and it has 236 x 387 px. Really donno why? Put the width to the <td>s. It's better. Your code is full of small->big images.
