Used to do a bit of Flash myself when I worked for a web design company. Fished my books out last week to do a splash screen for my site which isnt going very well as I seem to have forgotten a fair bit in 2.5 years

Firstly, looks very good, black especially.

My only tips from a personal perspective:

On the home page, you list "Arts | Landscape | Monochrome" - I thought that was the menus and had to do a couple more takes and hovering to find the "Enter" button.

Inside menu is good and very asthetically pleasing.

I would put the feedback form on a completely seperate page, the reason being, html buttons look untidy compared to flash which has a very clean look. I would perhaps have a seperate menu altogether for the contact/feedback point.

Oh and is that a dead person hanging in the first picture once you have entered?

HTH mate and definately a good looking site in the making
