Pretty sure this isn't an original. The character is Nefelia, from the "Maou no Ore ga Dorei Elf wo Yome ni Shitanda ga, Dou Medereba Ii?"LN.
Probably, the Pixiv upload didn't have a translated copyright tag, it does have the "魔王の俺が奴隷エルフを嫁にしたんだが、どう愛でればいい?" tag though which I assume is the LN you are talking about.

Yeah, that's the one. Proposing we change the tags? (Would do it myself, but don't know how.)
