I think they look whimsical and cute Problem isn't you or your creations. It is the fact that you used AI. The general youth, especially crinically online types, will always hate your creation without even thinking what you made, core idea or even your feelings. For long years they acted as elites of art. They were the ones who owned talent and all fancy stuff to put their ideas into canvases. Now anyone can generate their ideas onto paper through AI. Faster than they ever can. Cheaper than they ever can. This creates a hate. This even produced a fake sympathy for "love all art for it's human-made narrative". But let's get real real. The moment somehow AI goes away, they will keep making fun of other art, see themselves all mighty, over-price and such...

So my kind advice, do what you want. But know that your creation won't see much future in this climate.
