- Here's another growth for RedFur1322, this one is Nimbus 8)
I went ahead and grew the horns. Also, there are about 3 different shades of almost-black on the body, the darkest streak is on the shoulder, the middle color is on the head, back, and tail, and then the lightest (base) color is a marking on the head and most of the body. You may have to squint to make it all out (I did when I was looking at the reference XD).
