I like the flash header, but if there was a way to minimise the file size so that it didn't have to load for a while, that would be nice.
I viewed it using a 3MB d/l speed, and 2.5GB RAM in my computer, so it's a little incongrous that something should take that long to load up for me).

There's nothing else about the design I don't like. Maybe that the header of the page is a little big, but it's not killing the site.

You didn't ask for a content review, but it's not readily apparent to me what your site is for.

You might also consider having someone re-write the copy you use on the front page as it seems like gibberish to me.
I gleaned after several brow furrowing minutes that you apparently design gardens. Is that correct?

If I found it through a search engine I would admire the design, but I wouldn't stick around to decipher what the site was about.

Hope that helps some.
