Legolas has a son? w00t
Or Legolas is the son :D
Yeah, it reminds me a lot of the Elven King (Whose name I forget) design for the recent Hobbit movies.
Actually its signed "Thranduil" in the left top corner. Concentrate a bit and you could possible read it too :D Its greek letters. So its him, wood elves king, for sure. Kid is probably Legolas or just anyone. Maybe some tags must be added.
It's not even tagged or entitled pixiv_fantasia at the source... Heh, Flandre, you're so silly.
