The hard part about using Midjourney is coming up with a prompt. This prompt can be as simple or complicated as you want to make it, and depending on that, it will generate art matching the description you give it. The prompt can be as simple as "draw me a house", but it can also take in what I like to call "modifiers", which are additional descriptors, such as the color to use, the style to use, or even the medium the artwork should be done in.
Here is a list of modifiers that I compiled as part of my research in generating AI renderings with Midjourney. I hope you can get some ideas from this list, as I frequently do. Please feel free to send suggestions to add to this list through my Discord link at the bottom.
More on the way.
