I haven't looked at your listings yet, so this is just general advice for photos:
Get the kind of light that is called a "photo light". It's a bulb that is balanced to give you the correct colors.
It's better than incandescent (which tends to yellow) or fluorescent (which tends to cool). They are curly like the compact fluorescent, but use a different spectrum of wavelengths.
Do not put complicated patterns behind the items or highly contrasting colors. Don't try to "dress up" the background, use backgrounds that focus the buyer's attention on the item that is for sale.
Put a medium-gray or other neutral color behind items. White is not the best background color for dark items. it will throw off the white balance. Use a medium gray. The same for very light items.
Get a "tent" to smooth out the background and to bounce around the light so that the item is evenly lit on all sides. If your items are large or you don't want to pay for a tent, use a neutral-colored bed-sheet or cloth shower curtain (not bright white). Cream, light gray or light blue seem to work well. I bought large sheets of card stock at the art store in several different colors and rigged a post with a large bulldog clilp to hold the background in place.
One thing I suggest that not everyone agrees with, so take it for what it is worth. I do not try to make inexpensive items look like showroom items. I photograph $80 and up items as close as I can get to looking like they were shot by a professional. But I don't do that with $5 or $10 items. I try to shoot them well but I don't want to make them look like high-class items because it seems to confuse buyers when the "look" of the item and the price don't match. It depends what it is. For vintage items, I try to make the look of the photo match the quality and price so the buyer is not disappointed. I also try not to make tiny items look like they are big. Again... I don't want to disappoint buyers.
Best regards,
