Overall I find Artstation to be one of the most interesting places for contemporary art. Over there artists are generally followed by other artists so there is mutual inspiration. Not sure exactly how the visibility algorithm is designed but it seems to function decently.

conceptart.org used to have a dedicated section for artists working in traditional mediums, but I’m not seeing that on ArtStation
Nice to hear. There are hashtags for traditional mediums on Artstation but I'm not sure how often artists remember to add the appropriate hashtags.
I came across one artist on Artstation that built physical models of spaceships, in small scale of course, then there are some traditional painters also.
