Nice effort
Recently watched 'Last of the Mohicans' (the one with Madeline Stowe and Daniel Day Lewis) and have added this figure to my grey army wish list......
It has come together well, and overall, the scheme is nicely balanced.
I agree with the others; cut the eye white with either a grey or a pink.
If you want reference materials, grab a friend, take portrait photos of them as a head and shoulders, torso, about 6 feet away, 9 feet away, 15 feet away. (mae sure the shots are in colour, avoid flash if possible).
Over the range of photos, you'll see what details and colour shades change as the figure appears to 'shrink' with distance.
Faces and eyes I am learning to do too. What holds for a 54mm face is slightly different for a 120mm....
to practice (and practice again, and then once more).....I purchased some spare head sets, about 6 heads, and am practicing painting those....gets the focal point for a figure closer to what I want (although some efforts, I am happy to move away from not so good) without the $$$$ invested in a full blown figure.
Excellent start.
Remember; Jumping out of an airplane is Gravity and faith in the chute packer. Painting fine details require practice and faith!!
Keep up the effort!!
