I, nor do most other people, like those popup ads
The buttons are a little bland, and when pointing at them moving over the others, two will highlight at the same time.
The pictures seem to cut off a lot--maybe just seems like tha--but to me, personally, it makes it feel cheaply made. I'd just say contrast the colors and blend the pictures in a little better. Also note the colors of your text with the pictures, logo, etc. Make them match, nice 'n tidy!
Not sure if that's the kind of reply you wanted, but that's my "suggestions"!
Can't tell much more with just the main page there
Good luck,
