Yeah first off, the resulting image of this card is nothing like what I originally planned. All I had in my head was to have some swirly thing coming out of a pair of headphones.
Well, I drew the person wearing some headphones very similar to the ones I have in real life. I used a stamp that I just got for the swirly thing, but that had to come last because I had to color everything.

I colored the person and then decided to add an outline (because I love outlines on things) like a sticker. When it came to the bg colors, I had in mind to do a watercolor effect, but since I was working with Copics I stuck with the markers. Once the bg was done, I thickened the "sticker" outline and by then it was really looking something similar to Unknown's picture here.

So I guess it's sort of my version of UnknownRumor's picture.
