The first of your examples was generated on a desktop computer with 2080 Ti and even then still glaring uncanny hands. We don't know how long it took but I think the reason for the hands is that it's too slow to generate a dozen of these in hopes that hands would come out right.
The other one I can see done on any laptop in a few minutes, but it's more primitive and just a monochrome sketch. I skip over obvious issues e.g. with shape of glasses.
For both examples you don't need any specialized tools or watermarking to notice this stuff.
Maybe you see what I mean why indie homegrown AI is not such a big deal ;) Sure there are people who will invest in hardware but those people will are not and for now won't be mainstream enough to matter. Especially if it will be licensed, most people don't like to violate laws. Most people will just use chatgpt or dall-e.
