Don't get discouraged! Hang tight. We're all in this together. :)
I agree with Sue on retaking a couple of the darker photos. One thing I wanted to add was make sure your tags and titles are more relevant!
http://www.etsy.com/listing/83780333/beautiful-blue-silver-clear-crystalTry changing your titles so the first couple words (I think of first 3 words), are the words people search for. For example, in the above listing, instead of "Beautiful Blue Silver Clear...", try Blue Beaded Necklace, Seeded Blue Necklace, unique blue necklace, etcetc
Really try making your titles more relevant. As for tags, looking at the same listing, I would do the same thing. Make your tags a little more specific because with broad terms like "comfort" or "hook", people who are looking for blue necklaces, won't be able to find you!
Above all, don't get discouraged. This is a learning process and will get better the more you edit/add and advertise. Hang in there. :)
