If you're hunting for top-tier Raiden Shogun pieces, my usual starting map is a mix of Pixiv and Twitter/X. Pixiv tends to host the deepest, most polished galleries — search tags like 雷電将軍, RaidenShogun, or Ei, then filter by 'popular this week' or 'daily rankings' to spot artists who consistently put out high-res work. Twitter/X is great for one-off pieces, process shots, and short animation loops; follow and bookmark artists, and use lists so your feed doesn't drown.
I also poke around Reddit communities and curated Tumblr blogs for themed collections and fan compilations. For prints and physical merch, check Booth, Etsy, and artists' stores (many Pixiv profiles link their shops). Pro tip: save via bookmarks or a folder in your browser, and use PureRef or a Pinterest board to assemble and compare color palettes and poses. I always make sure to support creators when I can — buying prints or commissioning small sketches feels way better than just hoarding images. Finding a few favorites and watching them grow is part of the fun for me.
