A little dilemma

So ive been wondering

Should i post like demos of mine in YouTube (to look for some feedback yk)

Or should i just keep it to myself

I'm not scared of other people seeing My stuff (becausd ive sended demos and other things for opinions to close Friends) but i think this is different.

Just random people seeing My music and telling me that i suck or that it's great and should keep it on

What do you think i should do?
