Hi, Jane! I really like your work, but, I really feel you need to go back in and revise your listing.
1. the title should be a list of keywords that people will use to find your art, such as ex: LANDSCAPE original aceo bridge art by Jane or whatever you like, but, make the best possible use of each available character in the title by using only common search words. Not sure what is being used, research by playing buyer and see what you pull up using differant search words. There are also program available that will list common search words for you, not sure of thier names, but others here can help, I'm sure.
2. I found all the other artwork photos confusing. Is this listing for all of them or only the first? Be dumb/simple with your listings and make it VERY clear what the buyer is bidding on. If those are just samples of previous work, then you must make that very clear!
3. Use the discription section to talk about your work! List the title, medium, ground, any pertinent info such as what information is written on the front and/or back, any special process you might use, quality of materials, ect. Also, this is where you 'sell' your work! Say something about it, your inpiration, or mood, or anything about this work.
4. I forgot what you listed at, but, I highly recommend listing your work at a fair and reasonable price that you can live with. You won't always get 'bidding wars' on your work to drive the price up, so start your bidding at the lowest price you would be happy to recieve for it.
Good luck!
