Hello there! I like that you decided to draw boxes in a different way instead of keeping them as simple, plain boxes. When painting objects, try to avoid shading them using the same hue as the local color. For example, if the base color of these boxes is orange, avoid creating shadows simply by lowering the value and saturation of that same orange, since that usually results in a muddy brown. Instead, start by thinking in terms of warm-versus-cool relationships. If the local color is warm, then the shadows should generally lean cooler. Notice that when I painted the shadows, I shifted toward desaturated reddish tones. Also, try to avoid having both your lights and shadows highly saturated. If one side is more saturated, let the other side be more subdued and desaturated. Doing this helps create better color harmony and adds more vibrancy to your illustrations. :) Hope this helps! | Artwod Feedback
