help Custom ring is not at all what i imagined

I’ve never posted on here, but I’m desperate for some advice if someone has some!
I recently got engaged and had my wedding ring made by a jeweler. I found her on Instagram and had followed her for a while to examine her work and style. I wasn’t planning on getting a custom ring until she added a stunning diamond to her shop. After getting engaged (he used just a band) I approached her about getting my dream ring with that specific stone. We exchanged many emails about the setting and I thought she understood my design ( a simple solitaire in a prong head setting, but a tapered band). She just sent me images of the final ring and it’s not what I had in mind.
1. I don’t like the prongs, they are not what we agreed on at all. I wanted dainty looking prongs, these look like claws.
2. The diamond is not in a print setting like I imagined. It lies flat against the finger and I can’t wear it flush with my other ring.
3. The taper looks nothing like the rendering she sent me, which I approved (because that’s what I wanted).

I need some advice how to properly address these issues. How do I ask for her to change all this? From what I know about structure of rings she probably will have to start all over with a new ring? I feel like I shouldn’t be charged for any of these changes because it’s not at all like the rendering.....
