My son is mad about buses. Especially double decker buses. The higher the better. So I draw for him a four decker bus, with a small house top. He likes it so much, he now wants to get on a real bus like this and climb at the very top.
For this one, I used my usual style: black ink on paper digitized and adding the colour using my trusted illustration software Inkscape. Only, when the product was finished, I accidently removed the top layer containing the original ink drawing. I really like this paper cut-out look. Even the little white gaps here and there between two colours gives it a certain charm. The reflections on the windows are from real life original photograph of skies.
