WOW! Your dolls are awesome. I think your titles and tags look relevant for new relevancy search. Your pictures are pretty good too. The one thing that I thought, was I really don't think you need the sentence in your description about 'if you don't like what I've done...........etc etc.....' It makes it sound like your not confident in your work. Your work is excellent and right on the mark with matching your subejcts.
Have you been participating in any forums here or treasury making, and teams? it's a good way to get other esty owners to notice your stuff and then get featured in more treasuries........and so on. Also, are you doing any outside advertising or marketing? Are you using facebook to promote your work? There are all things you may need to work on. But I've have favorited some of you work to include in future treasuries. It's really wonderful.
