Is okay it okay to upload my own animations? I'm still a newb.
Hello? Anyone? I was wandering is it okay to upload my own animations? I've only done 5 uploads so far. I've been goofing off doing illustration instead animations, is that a bad thing? I feel insecure uploading here, feels like sakugabooru only wants professional works and not someone who's learning, struggling to be a professional. Am I wrong? Are there any regular sakugabooru users that wants to draw animations from their very own hands? I'm looking for a community full of animators drawing anime, to learn from and interact with.

Here's my animations, it's my only 5th attempt, I'm still learning. It's really 1080P not 480p. https://www.pixiv.net/member_illust.php?mode=medium&illust_id=72513929 .
It's dumb that pixiv doesn't supports higher resolutions like 1080p. And what's worse you have to limit 500 frames to fit it into pixiv. I want to make my animations to be like watching anime on crunchyroll. Are my animations good enough to be able to upload here?

I'm looking for critiquers on telling me on how to improve, draw better, and draw faster. Are there any nice people that can critique?
So far I found very few technical information on how to animate.

Like these links.

I think it's great, love Touhou fan animations. All I'd say is rely on onion skin more to keep the details more consistent.
As far as uploading, while unofficial works are allowed (Like the Touhou fan animes uploaded here), I'm not sure about self uploading, though self uploading is frowned upon on at least Danbooru
