This community is active and likes to see artists of all sorts. It's hard to tell where you will feel best, it's something you have to figure out for yourself, but you are welcome here.

Where are all the artists? Most of them changed and tried to fit in instead of going for a niche only.
That's why most communities for creativity didn't make it. You will find kinds of art with other communities as well, mainly drawings (contests) or photography (entries).

Who will be supportive is also questionable and the same counts for receiving comments and help.

The Tron Community is NFT "art" but I am not sure how active and supportive they are.
There's also WOX (World of Xpilar)

You can look around and also to which communities users subscribed.

I wish you all the best.
