hi there, I am new too... hmm... I guess I am not really in good position to advice as I only made 2 sales and haven't got a feedback from the buyer (makes me nervous).
Anyway, you said things u made had rave reviews! Hence, I thought your stuff should be alright. Other sellers told me to just do it, try posting daily (which I can't yet, sigh). Patience, Perserverence and do it with your heart. I am also in a delimma on publicity... cos I am nt a v social networking person... but I try to buy showcases spot and write in to blogs to asked to be featured. :}
