Overall I think your photos look great and I love your items!
On the screen I'm using now, the yellow on the flower below seems a little bright:

That might help. You can change that on your camera or usually in the photo editing software.
Again, though, I think they overall look really good and your items are so fun and pretty!
Let me know if you need me to expand on anything, or have any other questions. I hope that helps! I too am working on my photos, so I know how time consuming and for me at least, somewhat frustrating to get it just right.
