Trouble is your home page doesn't tell me much about what products you stock or even that you are an online shop (without reading all the text).
If you check out almost every large online retailer the first thing you see are products. Try Amazon, Woolworths, WH Smiths etc...
I also clicked on the 'our Shop' link and noticed you also have no image of the Wheelybug Ladybird. The image here helps the visitor decide whether they want to know more about thing the product or not.
There's also nothing immediately visable (which should be shown on at least the Shopping Cart page) as to how I pay you. PayPal, WorldPay, Cheque ....? The types of payment methods provided ultimately make a different to me as to whether I make a purchase or not.
Colours work well and the logo looks good
