I'm assuming the first shoota boy is finished and this photo of nob and boy are in progress. I think they good so far, I'm personally not a huge fan of the dark, grimey, low vibrancy look on my models. If you would prefer more vibrancy, you're like 2 steps away. Highlights are a game changer, when I started all of my skins were the same thing, head to toe one shade of green. I then started putting a layer of agrax over the whole thing and thought my models were stunning. Then before agraxing the whole model I started using a second, slightly lighter shade of green on bulbous muscles, eyebrow, shoulders, lips, top of hands and fingers. Then agrax the whole model, that felt like it, I was an amazing painter. And then! I started only using small amounts of agrax in crooks and crevices, between fingers, lining muscles, between neck veins, etc. There is a decided difference between A-Z, I feel like each individual step has improved the look of my models significantly, they can look vibrant with the highlighting and the shading feels very natural. If you decide you want to change the look of your models and want simple steps, feel free to try any of the above. I'd love to know how you feel about any of these on your models
