I am still looking into good resources for Godot but so far these two videos have probably been the most useful:
this one is a little bit dated and some of the code doesn't work in the current version of Godot, but folks in the comments have some good suggestions for fixes - helped me with figuring out how to set up a system to cycle through different options and load in the textures for each sprite correctly.
this I found useful for assigning colours to specific parts of the doll - the first part of this series mostly goes over how to break up sprites into different pieces and how to animate them consecutively, which isn't as relevant for a doll makerI am extremely new to Godot so there's probably more stuff out there I'm not aware of, but I think this is a good starting point at least!
