You have a custom prompt enabled (probably from viewing another one and pressing "start over") that is asking for opposites which will increase the noise a lot.
Starting over by removing the permalink parameter gives me much more consistent results! An exampe from before: https://dalle.party/?party=Sk8srl2F
I wonder what the default prompt is. There still seems to be a heavy bias towards futuristic cityscapes, deserts, and moonlight. It might just be the model bit it's a bit cheesy if you ask me!
