I gave it an image of my crappy art and asked what steps I could take to make it look better. It gave me specific advice like varying the line widths and how to use this on specific parts of the character. It also pointed out that the shading in my piece was inconsistent and did not reflect the 3d form I was representing and again gave me specific fixes I could implement. I asked for it to give me an updated version of the piece with all of its advice implemented and it did so. I was pretty shocked at all of this.
