How to make the bottom of the ring round?

Hi, i’ve been facing this problems for a while. so i wanted the bottom of the ring looks round/normal or not following the top shape? idk is it of my workflow or i just need to do some extra tweak.

thank you!

made another shape. just to be clear i came from this workflow. my goal is to make the bottom part looks round/normal if you know what i mean. kinda confused to tweak it since the shape is kinda complicated.
thank you!
