this is a 2d rig i made in firealpaca, you can use it for whatever you want..modify it add to it etc etc, of course it still needs bones added for puppet animation...you can use a free program such as "synfig studio' if you don't have moho..or anime studio.
im starting to learn how the snapping tools work in fire alpaca..i drew this stuff as practice...these are bitmap, so they're not as useful as vector for sizing but still very useful tools.
i try to draw at least 1 thing per day for my digital sketchbook,..i drew this in firealpaca while learning from andrew loomis books..i didn't use reference for the portrait side..but for the figure drawing i looked at an old daz studio pose, then made up my own hair clothing etc..
more random practice in firealpaca, these are only 8 frames of animation...i drew a turnaround and some other random goofy stuff.there are only 3 frames of animation for the girl walking her chad dog,..and only 2 frames for the mail truck..to make it look like the tires are spinning.some of its just scribbles to try to learn how things move.
