I took a whack at it too, and the best I can come up with is Mogumo, a mangaka (manga artist). Here is another group of Mogumo's art on another site; none of them is crow guy, but the style seems similar enough that I could believe the same artist did all these works. The same occurs here, but with the added link to pixiv suggesting Mogumo has since left that site. Given the similarities of style in all the works, I'm prepared to agree that Mogumo is the original artist unless solid proof of something else is presented.

As for sourcing, AtlantisUchiba can either link off zerochan or use Pinterest as a source but with a "see discussion here" afterward that links to your thread (or this one, if he'd rather).

Thanks, that was a tough one! I haven't had to dig for one like that in a while.
