I like it. It's got a nice slick style to it and looks very modern.
Design and Theme:
The menu buttons are fantastic and I really like them. I think maybe if you add a subtle hover effect to them it might enhance it a bit, but then again you can have too many effects on a website if you're not careful.
The icons beside the links are great, and can really intrigue visits into visiting your links rather than just thinking it's just another directory.
The background is horrible. IMO you should have a light background color with maybe some sort of abstract image.
Domain:
The domain could be potentially quite good, especially with the keywords Web and Directory but unless I'm missing something there probably wouldn't be a lot of people looking for a "Web Engine Directory", but I guess with the right promotion it could go far
Promotion:
Apparently with the correct promotion and work done web directory's can really become quite profitable. I think John sold one of his directories for quite a large sum of money a while back, so keep promoting (even spend a good load of money on promoting) and within time I'm sure it'll be really successful.
Overall: I'd give it a 6 out of 10 based on the style as I think you have a good bit of promotion and visitors to get to the site.
