Hi Brooke, I am only on one more month than you, so not one to give advice. I can share some advice that I was given. It was suggested I should have at least 100 items but no less than 50. In the beginning that seams impossible. I would work on getting a lot made and then post all together. After that, work on getting traffic. I gained a lot by the Beginner SEO and Boss Ladies teams. They have a lot of post where you post one of yours and then favorite several before you. It has brought me traffic. I have had 17 sales in two months and I am pleased so far. I hope someone more experienced will jump in here and help.
Your pictures look good to me and you used all five which I was not. Sorry I could lnot be more help. Good Luck and don't give up too soon. It takes time to get going.
