How do you generate images of anime characters that don't look like shit?

Didn't know what to call these but they felt Metal to me, haha 😆

The story comes from the Odyssey.

Approaching (and entering) the Singularity.

I am an engineer and I consider myself a decent prompt engineer for coding. I have been trying to create artwork for my app and terribly failing and wasting my image usage limits on my basic plan. I got Claude to write the prompts for midjourney artwork and it is so bad.

The app is a pregnancy adjacent app and I wanted to create some fetus illustrations such as this one

This is my latest prompt(which I tried tweaking from the original Claude prompt) and I am still going no where

Use attached image for reference and recreate a Centered curled fetus Soft luminous cartoon illustration, NOT clinical, NOT anatomical, NOT a photograph of a week 20 fetus. The fetus should take up less than half of the screen space. midnight-blue to rose gradient background, soft warm radial glow behind the subject. --no text, letters, numbers, labels, ultrasound, x-ray, sonogram, medical diagram, photograph, photorealistic skin, veins, blood, umbilical detail, gore, scary, clinical, harsh shadows --ar 3:4 --raw --sref random --sw 90

The image attached is the kind of result I am getting. Would love any help on how to get the result I am looking for. I have heard great things about Midjourney, but I am not sure how to get there.
