Lol, here is just fine. I usually put my crap on Art Share (originals using few/no collage elements), or Low Effort Memes (a blissfully permissive community that hasn't given me too much shit for my collage stuff yet).

I'm a firm believer that it's OK to be an amateur in public. Yes, you might get downvotes/people saying you suck/whatever. You might also get tips to improve, or encouragement to keep going. At very least you can point at something publically and say "Hey, I made this!". Maybe someone else points at it and says "I can do better than this", then picks up a tool to try and prove it. Bam - you just made another artist.

Quoting from noted philosopher Violent J: "If he knows what's so dope he should make it himself, and quit fucking judging every-fucking-body else"

This is a good start! Hell, this is what 90% of my drawings looked like when I was a young guy. At a certain point I stopped, and didn't approach art of any kind for decades. An old friend of mine at pretty close the same skill level kept doing it, sharing the results with interested folks, kept honing their craft, and now they're a professional animator with credits in award-winning shows. Thank you for sharing!!
