Great images!
I tried myself to generate some and it was a disaster. I guess you have to learn some tricks.
Try doing this and see what happens:

Found this hint on Youtube and that is what helped me to generate some of the images in OP. You can also find hints at Midjourney's Discord - chat - prompt chat or community forums - prompt faqs.
