quick look ...
the owen chubb ... logo looks slightly wrong ...
The images on each of the pages ... load fairly slowly ...
Your background image the green ... on the left hand side looks quite pixilated ...
Hmmm seems like overuse of background images for menu items as such they don't scale up nicely. recently I've started making a lot of use of ctrl + when viewing websites ... ( maybe I'm growing old

) as such I'm not sure if its breaking some useability guidelines ... (but that is a bit of a technical / useability issue as opposed to an actual fault on the site)
Its not exactly an online shop ... its an online catalog ?
You don't have their business number on the site ...
No link to your own website ?
Hmm... personally I'm not sure about it .. having seen the previous version ... it had a more friendly feel .. this has a more professional feel to it .... which may or may not be a bad thing depending on how you look at it ... but as I said its my personal feeling on it
