I tried DALL-E Mini, as well. it's interesting like a toy, but not for a masterpice, of course. It is funny how it imitates the Voynich style, but as much as I see, "he" is impressed mostly with circular diagrams

My nymphs and plants were always in circles, of strokes imitating text.
I signed up for the DALL-E and Midjourney waitlists. I'm still waiting for an invitation to try the DALL-E AI, but I've already received an invitation to Midjourney and have even used my free trial to experiment. Unfortunately, there were not so many attempts, besides, I immediately rejected several options. When I realized that this AI ignores numbers of objects (in this case, 6 towers) in the same way as the AI in Disco Diffusion, I finally moved on to other attempts. I must say that in other respects Midjourney clearly outperforms Disco Diffusion. Firstly, the generation is very fast, about a minute, first 4 options are offered, you can choose one of them, improve (finalize) or make options for the already selected picture, then you can upscale the desired picture; secondly, the picture is much more consistent with the text description than in Disco Diffusion, i.e., the AI generates the image more accurately; thirdly, there are almost no incomprehensible artifacts in the picture, only given objects. Well, I will add that Midjourney does an excellent job of generating human figures and faces, as well as animals. In general, the results impressed me, but I'm not ready to buy the paid version, so far.
Further, I also want to note the disadvantages, at least of the trial version. It takes place in the general chat of Midjourney newbies on Discord, you can only use text prompts, as well, you need to constantly look for your message (image) in the chat, as new messages from other newbies are constantly added. To be honest, I spent more time searching for my pictures than creating them, however, in the process of this, I saw many successful and interesting incarnations.
Nevertheless, I must confess, despite all the disadvantages of Disco Diffusion, it is quite good in landscapes, it is not so accurate in details, but, it seems, more creative and artistic. Little and far details are often blurred or deformed, but there is some artistic charm in this. And sometimes, it even seems that AI once works with inspiration, another time - without any enthusiasm.
My aim is a little differ, in general. I still try to make some Voynich scenes realistic. You can evaluate how Midjourney coped with my task:
