I'm really unsatisfied with my art lately. Especially my coloring and rendering feels really amateurish to me. I'm was trying for a vibrant artwork, but I feel like the colors are clashing. Also I struggle with using values and saturation in a pleasing way. The textures also seem really off. Any tips? | Artwod Feedback
