I already found this question, but it only talks about the kind of software used - not the actual methods. Were they drawn at a high resolution first and then shrunk down? Or did you just zoom way in? Do you do a vague outline first, then make it more detailed? How was the coloring done? And when you have to do long animations, do you hand draw each frame, or are there tools to help automate the process? Or do you just copy paste the basic sprite and only change the moving parts?
