Check in WC3 Validator as there are a few errors. Also doesn't work in IE8 and below which might be a bit of an issue as IE8 is the most widely used Explorer browser but of course depends on the brief from the client.
The page is too wide to fit on a 1024 res screen and the links on the footer overlay the supersizer links if you narrow the page. I would slow down the supersizer animation as it is a bit distracting from the content.
Re: The site is designed for a resolution higher than 1024, analyzing the different visitor statistics.
Sure depends on visitor usage capabilities. I still code for 1024 screens even though it is declining.
Screen resolutions are getting bigger and more complex now with retina displays. But they are also smaller because of mobile devices. Which kind of complicates things somewhat !!!
Wow! That is seriously gorgeous! How long did the development take? I notice you haven't listed CompanyDirectory - how are the artists' profiles entered?
