in truth midjourney does much better on smaller prompts than stable diffusion or dall-e which tend to do better with longer prompts, but my best results have come from image to image along with prompts. The secret superpower of midjourney is that you can use multiple images as image prompts (the rest can use one), first image becomes core structure and composition, second image becomes primary style, third is secondary style etc, but all influence the image. My best results have been from 2-3 images.

other tips: add on the end --ar 3:2 for wide image or --ar 2:3 for tall

most important part of prompt toward front, usually what kind of medium the art should be (coloring book page, stained glass, watercolor, etc), then describe the content and use photographer terms like portrait, landscape, or long shot to describe framing and what's in the image, things like background and foreground help too.

if you know much art or photography theory, it will give you superpowers over normal users.

take some time to look at other people's prompts on lexica and midjourney showcase, if you want to play with stable diffusion for free first I recommend playgroundai.com which only requires a google account for about 300-800 free spins a day (they throttle you a bit after 300), but I think it's a good way for people to dip their toes in the water, but midjourney does tend to give better default results
