(To write this down for posterity: 8 hours have passed since my last comment. Since then, TheBaconBot has made 'an upload'... This is where our story continues.)
I just watched 'Oswald the Lucky Rabbit in: All's Well That Ends Well!' ( https://www.newgrounds.com/portal/view/923953 ) and I have to ask: "Why...? Why would you have thought the Newgrounds community would not welcome you with open arms when your animations are THAT GOOD?"
I can only describe that animation as "shockingly good" and I'd be very surprised if it wouldn't win a trophy or two.
Welcome back, TheBaconBot!

You are the only person who can answer that.
If you have creative output that you want to share on Newgrounds, and you 'like' Newgrounds, then I don't see why not. :)
