Here is the new version darkened side by side with the lighter one. It seemed that it was a unanimous decision in response to Rod suggesting that it be darkened from the bottom to half way up the head. I darkened the bottom, up both sides and scratched back in a few highlights on the right. I also darkened the shaded side of the horns and a few more places in the fur very lightly, then decided the fur sticking out the bottom of the fence needed some shading.
You were right Rod, I diluted the ink very little and it was easy going.
Thank you everyone for your help, it is much appreciated.
Is this enough now, does it do the trick?
