After staring at that hand study for over a week, I decided to add to it and make it more of a finished piece.
As I was adding the water to the orange Neocolors in the background, I noticed the black ink was bleeding. Turns out I didn't use a permanent pen for it. So I went with it and added water to the whole hand.
For something that took less than 5 minutes to enhance, I'm happy with it.
