Limitations noted:
trouble with hands, fingers on most images
Occasionally bad eyes (heterochromia issues)
sometimes will create splitframe, multiple characters or different views.
Recommended negative prompts:
If drawing women models, prompt out:
2girls, 3girls
The need for "watermark" appears to be an occasional need. I'd recommend you prompt "child" in the negative prompts to avoid childish features.
That's pretty much it. I usually develop a prompt that differs between landscape vs people promtps and often they are different for each new prompt. You can look at my example showcase pictures for exactly what I prompted for positive and negative, and if you're drawing the same type of image you may want to consider a similar approach.
You may find that I use unconventional prompting like the use of "::", ";", "_;", "AND", "_" and varied schedules without using "[" "]" around them. This is because I use the open source A1111 and I coded my own update to the prompt parser which allows the use of these symbols. I don't think I included sequences in these images, but other images that I've posted in the last month will have them.
For more information about that please see this article, or view my profile and look at my announcements for my github page. If you're feeling in the giving mood, I welcome all support here on my buy me a coffee page :)
Thanks and hope you enjoy :)
