I know it wouldn’t have happened easily with Nano. Banana to keep things consistent across multiple images. I haven’t tried recently, but image generation gets progressively worse (darker and off base) as you generate multiple of them. So kudos for the amazing art.
As someone who had an interest in drawing as a child and have bought trackpads and tablets, but never had the time & developed the skill to actually create the things that I imagine, I completely understand what you did.
I know some people are going to be upset at model generated illustrations. But I think the alternate is probably, no illustrations. There’s a lot of unnecessary AI image slop all around and most add no value or worse makes you just avoid reading the content by their awfulness. This was done really well and I am not sure I would have read it fully without it.
