The idea for the illustration and the background photo were provided by the client. So I only had to build and arrange the 3D-models. The most complex part was the plane.
The money itself is only made of plains and cylinders that were scattered along a spline. The textures were a bit tricky since newer Photoshop versions refuse to open scanned banknotes. I had to used the good old Photoshop 7 to edit the textures.
