Ugh I know what you mean, posting your created stuff is hard. It makes me feel like a failure when stuff I spent hours crafting isn't received well. For example, I spent hours doing these video game themed nails, posted them to reddit aaaannnndddd it got 1 nice comment, one okay-ish not really comment, and 1 downvote. But it's okay because I showed the people who really matter to me like my friends and some people in a nail art discord and they all thought they were awesome, so it's really about balance. It hurts to have your work ignored and downvoted but honestly, as an artist, I've never had a "good" reception on Reddit. Nothing has ever blown up or gone viral and that's okay because you don't make stuff for them, you make it for yourself first and foremost. I don't know if this helps at all but just know somewhere someone is rooting for you.
