Hi Carrie,
I'm brand new here (joined yesterday) and still gradually stocking my shop, so I can't offer any seller advice. However, as a photographer and Etsy customer, I'd say:
1. You're right that there's always room for improvement in photography, and we all have a lot to learn. But you don't have to derive it all yourself, there are plenty of resources. Try Understanding Exposure by Bryan Peterson, From Camera to Computer by George Barr, and almost anything by the publisher Rocky Nook. Study 500px and photographers that you admire to see what it is about their pictures that appeals to you, and why their images work. Get books of just photographs and spend time looking at each image.
2. Your images appear in batches of very similar work, which could be overwhelming to a customer. Sometimes too much choice is bad - you make the decision on which is the best (of the bee on the daisy, for example) and offer just that best one. (In my opinion, it's this one:
https://www.etsy.com/uk/listing/192069862/8x10-bee-photo-bee-photography-flower?ref=shop_home_active...3. Try some still life compositions to improve your subjects. Instead of plain shots of flowers, try taking a collection of petals and arranging them into a shape or word, something that people would like at home. The website Petapixel is a good blog for finding creative ideas by some of the worlds best photogs.
Good luck! When I have finished my store in a couple of weeks, I'll probably be asking the same questions.
