CAD review input pls

[tkeg11]

I have my CAD file from DK. It's my first time so wanted to ask for input on the design and numbers.
I originally thought I would go two tone, but I'm leaning towards all yellow gold. I had one jeweler tell me a two tone requires soldering the two pieces together and is a bit less secure as a solid cast ring (one color). Plus, I like the singular color in the inspo pics. The prongs will be more petite than in the CAD, I'll post an image of the inspo ring too.
Also, I tried on some sizing rings, one jeweler told me 7.75 ring size and the most recent had me try on a 7 and 7.5. My thin wedding band is a 7. It's loose at night and snug when I wake up in the mornings. I plan on stacking this new ring with thin bands, I'm thinking 7.5 ring size instead of the 7.75 I originally told DK.

I love it! I’m not an expert at all but just got my finished ring pics back from DK and they are to die for. I don’t think you can go wrong with him!

My only recommendation might be to make the shank a little bit wider. 2 mm on the CAD will probably be under 2mm when it’s all said and done. That’s pretty delicate.

How much wider would you go? 2.2 or 2.4mm?

I suppose it depends on the look you are after.

Pretty much the inspo pics attached, haha. Simple, classic, vintage-y.
I asked him about a milgrain knifes edge shank.
