I started experimenting with Midjourney a few months ago. While it does have its quirks, I found it to be a very useful solution for creating "original" artwork in a very short amount of time. In my case, making digital flyers for Sunday Sundowns. I'm one of several designers who make flyers for the event, so there's no unified branding or style. I can make whatever I want and change it up from time to time.
Have a look!
