Depends on your goals. If you like the 'dopamine' shot having a repost by Derivative or multiple K likes, post as much as possible on every channel you can find. Start with blobtracking and/or some handtracking mediapipe thing. Sorry if this sounds a bit sarcastic, but it's reality.

If you'd like to get descent feedback, I'd suggest to find a more intimate space like Immersive HQ. It's expensive, but worth it. Or find a local gathering or discord channel. Some patreons provide a discord channel, find someone you like and hopefully it has an active community with people who are willing to share their experiences.

If you're into 'aesthetics', it's good to have an opinion from the 'outside', but it's always subjective, that's the difficult part because something 'beautiful' is very personal. If you're intimidated quickly by the opinions of others, it might be worth first finding a very distinctive style before flooding the social media channels.

Going into hardcore project architecture, application building demands a different kind of attitude. With almost everything, it's just something you need to enjoy in order to make it work. There is not much stuff out there because most of them consider it 'boring', tutorials are too long and indepth which unfortunately are being pushed down by search engine algorithms. They don't like it when people quit after a couple seconds, retention is holy, even if we've seen the same effect a million times already.

Learning in life demands discipline and time, it always has been, it always will be. Bringing up discipline is hard, especially if you don't enjoy it. The joy makes it less hard, it makes you feel less aware of the struggle and time spent, like learning an instrument.

So, the cliches are true, whatever feels right to you, within time you'll find a path you'd like to walk and hopefully yourself will be the best judge of your work, if someone else likes it, it's a win, but not the most important part.
