So here's a perplexing case. While the artist's name is clearly on the image (and punching that into the artist database did give me a name with a similar style to this one), punching in the Weibo name brought up nothing in Google and I didn't find using the QQ ID very helpful, so I'm kinda at a dead end here (not helped by having to dodge variants of this with a third-party watermark).
Hence, check artist. Please don't hesitate to correct if found.
