I'm sure a lot of people already have seen it before but there's this social platform called ArtStation where mainly professional artists post different pieces that they've finished or are working on. It's sick because it's basically a huge database of great art and you can sort it through genres like fantasy, architecture, environments, etc and I find it soooooooooo great for inspiration when im about to start producing.

check it out it's pretty cool!
