I love the drawing! I might put it in the gallery in the phase 3.
For coding, I don't really do a whole lot of things different from most Sprunki animators, but what I will say is that using the variables and custom blocks a lot help a ton!
For sounds, I use BandLab because it is so much easier than FL studio, and the only tutorials I've ever followed was someone telling me how to make a bonus and extra character, so I'll put the link right Here! (it seems silly but I promise it works so well lol)
