Welcome to the forum...
When I looked the homepage it didn't work very well at all for me in firefox.
Now I think I know why it isn't working very well and that's because the 'animation' is tied into scroll speed and that just didn't work with me, my mouse accelerates scrolling the longer I scroll so my speed is not consistent (pretty common on windows too I might add). I think it would work better if you scrolled to each 'panel' of the animation then had it do it automatically, the 'droplet into coffee' was literally a stuttering set of images for me.
The link to the other page isn't really clear either, skip what exactly there's nothing really saying what you do.
When or if you do click 'skip', the navigation on the gallery pages seems convoluted and inefficient. I kept wanting to hit the Graphic Design, Webdesign, Motion Design and Art direction at the top and it didn't do anything while the <> seemed easily missed. It just didn't make me want to keep looking around and even contact you... which you could argue is the whole point of a portfolio site.
If I was to sum it up I'd say for me personally you've lost usability by focusing on adding 'fancy stuff' to the design of the site.
I also have a view that in today's market you need to have a 'mobile' friendly site too.
