Really cool character design. I like that you’re using a limited colour palette and thinking about texture. The main tip is to use reference. If you want to make something look like a type of material, such as leather or metal then you need to study from reference. Look at how light interacts with it. Is it shiny? Is it matte? Does it create a lot of wrinkles and folds? Is there a texture to it or is it smooth? Metal for example can look like a polished mirror and will have very bright specular highlights but have muted shadows. Burnished metal on the other hand will be dull and have a lot of surface texture. I touched up some of the metal parts on the character by adding stronger highlights. If your colours are looking “flat” it’s probably due to a lack of contrast. There is a push/pull effect between shadows and highlights. Shadows push objects deeper into the canvas whilst highlights pull them out towards the viewer. So have a greater distance in value between your deepest shadows and your highlights will add depth to the image. Also shadow tones are often warmer in hue than the base color, whilst highlights tend to be cooler. For the skin, your base tone is fine but your shadow colour is a little too desaturated and lacks contrast. I changed the shadow colour by taking the base colour and made it darker but more saturated and I then moved the hue towards the red. I did the same for her hair. I made the shadow colour darker, more saturated and redder. For the highlights in her hair I did the opposite. I made the base colour lighter, less saturated (because direct light tends to wash out colour) and moved the hue slightly away from the red. | Artwod Feedback
