Agreeing with yo. I like the line quality and contrast for the mice. It would be good to practice some text callouts to point out key points of each design. Of course, most of them are form studies right now, but when you push what yo says, there is definitely room for explanation of callouts, etc. Arrows to show finger movements… Don’t forget to draw hands to show scale! Very difficult things to draw, but you gotta do it some day.
