Hey there! I LOVE these characters!! They are so fun and characteristic, and I love how you placed the graffiti guys looking to the left and the cop to the right I think in terms of colors you can improve this: 1. Add saturated reds to the skintone (cheeks, elbows, arms) 2. Saturate the shadows more (the light is cold so the shadows can be warmer and more saturated 3. The pink outline makes it really fun so I enhanced that too 4. As for darker skin tones, use more saturated shadows and blue highlights for contrast But overall I think these characters are a BOMB | Artwod Feedback
