>>58666371So, disclaimer: Corbeau actually is difficult to render because he does not have much Danbooru content so his tag doesn't provide lots of pre-learned content for the AI to reproduce. To get Corbeau looking well, you have to pair your reference image with very good individual character trait tags.
'purple hair', 'hair fronds', 'angular eyes', 'gold eyes' 'angry expression'
And then pair those tags with a reference image in NAI
My suggestion for you really is go ahead and do a NAI subscription and start making stuff for yourself. And yes, the stuff you make will look bad to start. Your art will improve as you learn and you begin to teach and reference the AI with what you learn.
