Aaah right, and they didn't rescout you officially... I don't think it'll be a problem to keep what art you have, but if you put out some impressive work from now on I'm sure someone will pick up on it again. Changing styles and trying new thing's the way to keep evolving.
Good luck man! No reason to get rid of the old topic though, just start a new if the aim's been changed.

Well that sucks. :/ How can you unscouted someone? Only mods have that power, but basically: https://ornery.newgrounds.com/news/post/388624
Maybe it was the guy who scouted you; maybe they didn't feel your work as on par with portal stuff... only way to know for sure is to reach out to a mod and ask. There's a list of them here (art mods): https://www.newgrounds.com/wiki/help-information/site-moderation
Hope you get back in again in time though!

I was scouted by that one person who scouted about thousand of the artist, most of them (no offensive) are mediocre (not bad but need a lot of improving) and I was one of them. I would like to get some feedback so I can stay on Art Portal longer. In most chance, I was pruned. I carefully read that guide once more and it could that my old artwork may be the cause of it. Honestly, I always changing my art style to see if it fit for me or not.
I can ask the mod as of why I was unscouted but I probably know the answer.
I see what I can do to get back to Art Portal. Probably get rid of my old art thread and start creating the Crique thread instead. Therefore, I can get the criticism that people give to me and improve from there.
