I'd seen this OnKey before and thought it was just an anomaly of awesomeness. But then I recently found a MinKey in the same style and now I'm pretty sure this artist has done more work.

Unfortunately I can't make out what the signature says (AJAT?? AAJT??) ...Or maybe it's another language? It doesn't look like hangeul, though.

I'm completely blown away by the use of watercolors and how accurately some of the features have been done. And I'd love to see more of their work.

I've tried dA but I get the feeling this person is from pixiv.

If anybody has any idea of who the original artist of these is, please share. I'd appreciate it.

Thank you for your help~
