It's not clear where the light is coming from. The bright spot on the head is kind of from our right and behind the figure. The top of the head is dark.
The bright spots on the shoulder are on our right and in front or maybe just from the right.
The bright spots on the boots are from the top.
Way too many colors.
I did a quick edit on the head and chest. Then I started on one boot, but it was a bit tougher to get correct. I did not touch the hands, but they also need work. Hope this helps.
