Took advantage of Painter's iterative save function to record the process of a quick demo painting for a class.
I used that same sketch of a paper tea cup to make a sort of sloppy framework sketch
Blocked in the colors, mostly for the sake of value
Redefined areas and tones
Started finessing, adding detail and brightening and darkening areas
Last one. Worked in a tiny bit more detail and added some cooler hues to the shadows to balance out the green-y yellow.
It's still just a color sketch, but I think I'm good with it.
