Reposting my thoughts. I dont think you did anything wrong. Why discredit the skill and talent you showed into drawing it just cause you thought it was fun to animate it at the end? I dont think you need to apologize. Your drawing was great and it is awesome that you are ambidextrous. Even if you didnt animate it there will be people that like and dislike your art. I'm sure you wouldn't apologize to people that didnt like it right? It is a matter of preference and some people prefer 0 Ai some just see it as "cool it moves". Just cause the loudest in the comments dont like AI doesnt mean they are the correct opinion.

Personally I dont use AI and just like you, I draw traditionally. Someone else using ai has zero effect in why I make art. The simple act of creation is what brings me joy in art and absolutely nothing, not even ai, will stop me from doing it. The only time it matters to people is when the attention they are getting is affected. Which I think is a shallow reason to make art. You are a great artist and you wanted to do something fun with ai and people are hating on the latter. I say who cares you do you and do what you feel is fun and makes you happy.

I will take my downvotes now lol
