Who doesn't? :) Have you used Flash to creating this illustration? Or do you have those vector-ish brushes in Photoshop?
Ah, I just used a customised photoshop brush (a chalk one, I think)! :)
Well, it looks great! Have you uploaded it somewhere for others to use, or is it your secret personal brush? :D
Oh, it's no secret, but I don't think it's customised enough to be worth uploading! It's literally just the size 36 chalk brush (on CS5) with the 'dual brush' and 'smoothing' unselected, and the texture settings fiddled with a little bit :)
Studio Ghibli movies are a classic! :D
