This is my site http://www.webdesignmegastore.net let me know what you think, its based on oscommerce

Its a little difficult to read the webdesign mega store title, if you increase the fontsize for the it will help it and it will also help the look of the site as it will give it a focal point.

 

The headings for the pages don't sit very well under the grey navigation. If you move them down and give them a little room at the top it will look a whole lot better and less crammed together.

 

What is the point in having enlarged versions of the sites you offer when you can't see the site in detail. Make the images bigger images when someone clicks to enlarge, chances are people will want to see the sites before they buy them, rather then having to squint to see the detail you should let them see them in some detail....oh you have a demo button, that took some locating you should emphasize that button some more so that it is noticeable.

 

 

 

Also you should check this link

 

most of the errors are just down to you not closing tags off, but if you are producing websites for profits you should always make sure that they are valid html..this way they have more chance of working correctly in future browsers and means that they are accessible to all.

improvements i would make:

* make the logo bigger - about twice the size

* add some padding between the menu bar and the "Welcome" pink text.

* put a more definite boundary between the right and left column, maybe having one of them with a different background

* put the quote in a different colour, possibly in its own content box.

* center the thumbnail in the right column, put them in a grey background colour - poss glossy/gradient

* make the headers bigger

 

thats about it for now.

overall it is ok - it will do, but it could be better.

Excellent, thank you
