FRien said: Umm. No. In fact, ZUN never draw Iku. It was Alphes (not sure of the name) who draw Tenshi, Iku, Suika, and Catfish.
Maybe in DS, ZUN make portraits for them (except catfish), but all the drawing in the fighting games aren't from ZUN.
I know that, and I also recognize that this isn't the drawing of Iku from the fighting game.
In a recent interview with ZUN, he demonstrated as he drew several drawings of characters such as Iku, Tenshi, Marisa and Yorihime. This is his drawing of Iku, albeit the one in the video just showed the pencil sketch. Either ZUN coloured this or someone else did, but the rough of this drawing was done by ZUN himself.
And looking at the editted tags, I see it was drawn by ZUN and coloured by cynthia2. I guess that does mean it is technically mimicking his colouring style. Good enough.
