2D Hand Turn - Cartoon Hand Sketch

I then sketched my cartoon hand on a new layer, using my real hand animation as reference. Here I have done it on 2s, but I then sketched on 1s and cleaned up the lines for accuracy.

I also altered the cuff so it didn't move all over the place. The lines do still 'boil' a little as it is the sketch layer, but this will be cleaned up in the final line art.

This is how I used my hand animation as reference for my cartoon hand animation. I used it to find where each finger would be positioned if I had 3 fingers.
