Claire I feel for you. You are obviously trying your hardest to get this right and you will get there.
Don't imagine, however that a Flash website will be the answer to your prayers. They look pretty but they don't often sell very well.
You absolutely cannot make a website simple enough to use and you must concentrate on making every aspect of it straight forward and self explanitory. If even the most inept person you know can use the site then imagine how much wider you make your potential market?
First impressions on the new site are that the links look clickable but they all run together so that I am not clear where one menu item starts and another ends.
You could reduce clutter by putting the 'links' link at the bottom of the page, the Buy online ought to be redundant because the rest of your site should simply scream with places to click to buy online, the home button is better placed top left and you can make your logo a home button too.
I am not keen on the background colour and feel white is always best - it gives a sense of space as well as being easier to read from.
You have done a good job of turning the copy around to what the visitor wants but there is simply far too much of it. Remember it is afact that visitors give a website 3 seconds before deciding whether it for them or not. Show them something fabulous right away.
I reckon what would be a complelling thing would be to see one of your pictures hanging in a trendy bar. Actually see what the work is like in situ.
If your Clarice Cliff stuff sells than you should also feature this on the home page as you should always feature your best selling stuff in a prominent position.
From a selling point of view your prices are not displayed early enough. The shipping is not clearly displayed. You could put this at the bottom of the thumbnail page.
Your Buy Now button would be better if it was much bigger.
You don't have a Frequently Asked Questons page. Have a look at ours, it is based on actual frequently asked questions we have received. It is a useful way of reducing answering the same old stuff every day.
