Preface: can't link any images right now since I'm at my work PC

One thing that's become apparent as I've been playing around with MJ is that the prompts really don't matter that much at the end of the day. There's people out there who run around claiming they've been tweaking and crafting prompts for hours upon hours... but because MJ's understanding of prompts is so limited (relatively speaking) you can use a four word prompt and often end up with better or equal results to some fifty word buzzword-laden convoluted prompt monster.

What MJ is very adept at is picking up different art styles and artistic references (say, you want something to look like Mike Mignola drew it) as well as different forms of lighting. What it is very bad at is the staging of a scene or image. That is, the perspective. The scope of the desired image. What exactly is important in the prompt. Actually picking up on all facets of the written prompt (ie., just because you write it doesn't mean it'll actually use it).

Conclusion: for playing around and getting some ideas it's a nice way to spend time (and money), but if you really want something specific done to reflect your ideas? Commission someone for it.

Point in fact: I've had MJ put together character images for many of my OCs for a BTech fanfic I'm putting together. It's fine enough for that as long as you stay on the surface level. But the moment you go deeper? I had MattPlog on DeviantArt do a 'mech illustration. At this point in time, you can't really beat human talent yet.

One thing that I really like, stylistically, is MJ's attempts at lineart works.

Hmm, what prompts are you using? I've tried MJ but it gives me shading instead of lineart no matter what I ask for, NAI gives me significantly better lineart even though the compositions are worse because it doesn't insist on grayscaling everything.

There's always shading involved, like in the piece above. I haven't gotten anything that's just purely the lineart yet.

The prompt for the piece above was simply: space battleship above a planet, lineart sketch

Hmm, having to keep working to figure out how to get it to give me pure lineart then.

Amusingly I finally got it to give me some straw huts... when I asked for an empty beach with palms and it threw up huts all over the beach.

It also seems notably hard to get trash in a picture. This is what it handed me when I asked for a comic-style filthy trash strewn alleyway:

Reinforcing it with a stack of synonyms worked better, telling it to include trash, garbage, debris, and litter finally got closer to what I wanted. Shame it then malformed the dumpster and trash barrels as badly as it usually does hands.

I did finally manage to get a masonry wall, though no crenellations, and it can't make its mind up if the wall is brick or stones. This one was NAI which seems to understand lineart better than MJ. It still took half a dozen tries to get it though.

One other thing I'm noting is that the AI really, really doesn't like it when you ask for images in any size but 512x512px. I typically work in 1024x1024 as a base and then cut down from there, but it's not just four times as long to produce one that size but at least an order of magnitude longer.

As I move on to trying to make urban backgrounds I'm discovering that power lines are its hands when it comes to those scenes, it doesn't send power lines in any logical direction, they often dead-end or split in midair, and it not too unusual to find power lines transform into giant spider webs, a pattern of cracks in the sky, or tree branches.

Just posting a random sample from my library.

This was done back in MJ v3.

Man, Brazilian plane designs are downright awful. ;)

This one is interesting because it managed to parse a prompt I genuinely did not expect it to be able to understand (A scene of poor buildings in disrepair with a background of high-rise skyscrapers) but also randomly made it black and white without being asked, and of course it has the Urban powerline problem.

This prompt was a pawn shop drawn in comic book style. I also specified a view from above but it doesn't seem to have understood that part. Asking for comic book style is extremely hit or miss and a random selection of four from the prompt might well hand me black and white, something like this, and photorealistic all in one batch. I haven't figured out how to consistently get this style yet. As before, powerlines are an issue and here they seem to have become cracks in the sky, but the skyline is simple enough I could edit it out (along with the gibberish text) and fix it in post if I wanted to use this.
