a lot of folks I followed on DA back in the day haven't posted anything in months or years, and looking at the new postings is like browsing an elementary school classroom wall. I mean, I'm sure there's

plenty of good stuff still, but it's buried in an avalanche of um, less good stuff.

I like cg hub

there are sites like this galore.like this one www.conceptart.org/forum...

cg hub or conceptart for fantasy or game/industry orientated artworks. Tumblr and instagram (and FB) are my choice nowadays

for 3d Renderings people often use Renderosity

though they also have categories for writing, 2d art etc.

great, thank you!
