I was kind of surprised and really happy with the way the short and medium fur turned out.
I liked the idea of mapping the values. I am a detail person, but I think I got a little lost while working on the defined scales and wing feathers individually and I did better when I used your concept of mapping the value first. In the end I felt like I needed to do some washes on top of the painting to adjust the values. On a side note, I've got to say the eyes were really fun to paint!
