Hi Hannah,
Renewing daily used to have a significant impact back when recency had more weight in search results, but these days it's not really very effective. You can sometimes get a tiny boost from it, but you'll have to decide for yourself whether that's worth the extra money. You'd probably be much better off simply adding a new listing every day or two, though.
Your photos look fantastic, and I'm sure getting some modelled shots will only help.
Your SEO still needs some work. It's far from terrible, but there's definitely room for improvement. First, remove all single-word tags. Seriously, just get rid of them. They're useless. If you have "handmade bracelet", "handmade", and "bracelet", then two of these tags are redundant. A phrase tag is relevant for a search for any single word within that tag. So that's step one. Step two is getting rid of tags that match the category you've posted the item in. If you posted in "beaded bracelets", you already get a freebie "beaded bracelets" tag, so you don't need to add a tag for "beaded bracelet". Incidentally, plural and singular forms of words are treated as identical by the search engine, so bracelet = bracelets.
Now that you've freed up a few tag slots, you can get creative. You've covered the more general searches, but what about the specific, refined searches? Sure, "beaded wrap bracelet" might get a HUGE number of searches, but it also has a HUGE number of results, so a savvy (or picky) shopper will refine it further with modifiers. Maybe a small percent will search for "beaded leather wrap bracelet", and a different small percent searches for "blue beaded wrap bracelet", and another small percent goes with "minimalist beaded wrap bracelet", and another small percent tries out "blue ombré bead and leather wrap bracelet" (whew!). All of these small percentages add up to a lot of eyeballs, so you want to try to capture as many of those as possible. Most of those refined searches won't fit in the available tag space, so you break up the phrases in clever ways to cover as many combinations as possible.
Once you've made some tag changes in some of your listings, you can wait a few weeks and see what your stats page tells you. You can get a sense of which kinds of tags are performing best for you, and then start adding those kinds of tags to other listings while removing the less effective tags.
