Edwine Ernest,
The first thing I notice is that your listing thumbnails don't include much of the actual flowers. Given that this is what you're selling, you may want to rearrange them (Listing > Edit > Edit Thumbnail). For promoting advice, I would look into posting a coupon to make it worth it for someone who doesn't typically look at faux flowers and think 'Hey, I should try this. It can't hurt'.
Barb Kramer,
I'm not sure that it is so much that you are using the wrong tags as it is that you don't look like you're using enough of them. From what I can tell you're not using the maximum amount. Try to think of what you'd search to find that item. For example,
