Rather than doing art I've been "collecting" art in the last few months on Pinterest, categorizing a certain kind of fantasy art that I can use as inspiration and character portraits for my RPG sessions, not everything but just those that reach a certain standard in quality, originality and cohesive. So far I've
collected over 2000 "pins", usually trying to backtrack images to their artists.
I think overall it was a very positive experience, got a good grasp of what artists post their art online, that the majority actually doesn't. Artists that do artwork for books and games and the likes generally seem to not to do that. There are some 20 or something artists that have a lot of great art that fits into the collection, and then there are a few hundred artists that have a single great piece that fits in, but whose remaining art doesn't fit, quality or theme wise.
I don't reference it too often, but I think the collecting itself made me understand what makes great art a bit better.
