I made a set of sprites to depict Count Digula digging (see attached file) because I realized in the designing some lesser diggle vampires that Digula's sprite set doesn't have a digging animation. However, I realized about halfway through that the sprites I was doing were smaller than the regular digging sprites; mine were 64x64 px and the regular digging sprites are 96x96 px. Also, if I expand the background canvas size, how should I position the image in the expanded canvas, left-justified, right justified or centered?
