>>24761683 said is pretty much correct, there's no real perfect site for finding art, it just depends on what type of art you want to find, and how much shit you're willing to sort through.
Pixiv is probably the best site, normally has a lot of good art, but isn't completely free from bad art either. Primarily eastern art.
Tumblr is the biggest site for western art, and while it's got bad art too, the main annoyance is ignore all the text post shit and RP faggotry you'll find.
Some Japanese artists also post sketches and stuff exclusively to twitter, so if you like an artist, consider seeing if they have a twitter account.
You could probably skip FurAffinity if you're not looking for NSFW stuff, but every so often someone posts an ok SFW picture there. Filled with terrible fetishes and furry stuff though.
DeviantArt occasionally has a few good pictures, but it's actually filled with more terrible fetish art and lack of skill then FA somehow. Good for finding uncropped resolution images though.
Nicovideo/Seiga is a smaller Japanese website that sometimes has some pictures that pixiv doesn't.
InkBunny is also a smaller website, similar to FA but with less frequent art posted, although there's a bit less fetishy shit in the Gardevoir tag.
And last of all, once in a blue moon, these Gardevoir threads will produce some OC that don't end up being posted to an external website.
I'm the guy who has collected 6500 images
>>24752363 and the only real difference between someone with a smaller collection and someone with a larger collection is how actively they search for new art themselves instead of just waiting in these threads for it to come to them.
Hope that helps you.
