Here's my entry of Amaterasu's growth. It's based only on the cub ref since there were a few changes to the design on the official adult ref (including addition of butt fluff and a whit marking on shoulder. I will add a version including the butt fluff + shoulder marking in a bit.
edit* for some reason when I go into oekaki, the lines are really pixilated. Then when I view the image it's not as pixelated... It's affecting the smoothness of the lines and color, so I will look into fixing it and then smoothing the colors (for example the blue toes and tail stripes)
