helloo, Overcast is a very tricky lighting scenario to paint, I tried to maintain your value structure as best I can and pushed for more contrast by presenting more occluded shadows in gaps where it makes sense, Also because overcast difffuses the Light source, we actually see more softer shadows and more midtones on edges where the form Turns away from the camera. I also noticed how hard (sharp) the shadow is on the neck, which usually means the light would have more strength, if you'd like to go down this route then I would suggest making the areas of light Brighter to justify the hard shadow. that you would have clearer distinctions of Light midtone and shadows. | Artwod Feedback
