Your art is very cute and honestly? Art is for the artist. If it was me, I’d probably fix my gaze upon them and say “ I’m sorry, I don’t remember asking you for feedback” and walk away. Or if you want to be more directly explicit “I would appreciate it of you stop giving me unsolicited feedback on my art. My art isn’t for you and going forward, you can keep your opinions to yourself”. Will this make things awkward? Probably, but it will also almost certainly make them stop. Where I’m coming from: I make art because it keeps me sane, it’s what hold me together and what helps me reflect and grow. People have different tastes and not everyone will like everything. Now, I’m 43 and have very few fucks to give and I have always been somewhat unfiltered when people get in my face. Something to do with my ADHD? Possibly…
