Love the leather!
If i may offer one critique? The hair tones, fur fringe and arrow fletching are very similar in tone, this would be a good place for breaking it up a bit ( maybe lighter tones for fletching and some browns for fur? )
I have been told by many to take every opportunity for contrast and separating items
for example the tones in your green shirt and brown leather, they separate nicely and add to the detail. You can see they are separate parts from a distance.
if i may ask who makes this bust?
thanks!
