Yeah, I have been approaching them individually too. And I think you picked the 4 I used most, so that's good! Makes the most sense, i guess. But I still feel like I'm just guessing or reaching too far.
Seems like "cute" might be too broad?
I LOVE your work, Bonjourpoupette! I can see how you're in the same sort of indefinite place as me. It's not as easy as if you were naming clothing or decorating styles. But, I would use tags like: Kitsch, folk?, woodland. I like how emotive your animals are - that seems like something that definitely sets your work apart from other cute animals stuff.
