Hello, Nice painting, I like it! =) Here are a few suggestions: Check the light source. From which direction is the light coming? Try to define a clear direction. You can look at the cubes I added as an explanation. I painted a small example for you. I used extra dark shadows on purpose, so you can clearly see the differences. Try to study the differences between materials and how they react to light. Pick a reference and try to paint it with a simple lasso tool, or only with a hard brush. The goal here is not perfection, but to understand how the material reacts to light. If you want, you can contact me by message for further help. Happy painting! =) | Artwod Feedback
