Lilsugarmuffin,
Here's an example of what is being talked about (I hope I'm not overspeaking someone) -
http://www.etsy.com/listing/88124099/fridge-magnetsExpand on that title by saying something like "Refrigerator Magnets, Fridge Magnets, Original Artwork Magnets, set of 3"
In your description you aren't really describing these items. What is the magnet like, what is the plastic 'case' (?) like? This would be the place to mention these are reproductions of your original work.
You photos look very creative and cool, but they don't look like a real object I could hold - they look digital. Maybe your photo is blown-out and you need to fix your lighting.
For tags I would get rid of: London, UK, 2x4, set of three, reproduction.
I would add instead: high fashion art, illustrated women, illustrated ladies, abstract art, digital art, refrigerator magnet, paper holders, and any team names you are a part of.
I hope that is helpful. You have some really neat artwork. I wouldn't give up. Each listing is .20; if you are feeling a pinch set a budget for yourself each week for an amount you can add, but try to add as often as you can. Join circles, teams, and make treasuries to make yourself known to other sellers.
