Hi.
I think it is OK. In saying that I can't say much because my own website is neglected!
The menu background looks a bit blurry and I don't like the choice of colour (for the menu).
Also the pencil image is very low quality.
The slide transition effect is really cool but I think it's moving too fast.. I barely have time to take in one slide before it is moving on to the next.
I feel like the drop shadow under the blue part of the background should be removed so the blue just suddenly stops to white. Then put a drop shadow on the 'page' part. It looks like there is a page floating in front of the background but you can't see the edges.
Use CSS3 for rounded corners and drop shadows. IE7 and IE8 doesn't support it but never mind, we are all moving on. The page will still work without it. It will save you lots of messing around with images and make the page load faster.
You need a logo! I don't like the text at the top that says websajtovi.co.rs
Well, there's a few for consideration. Keep it up!
Le-roy
