Hello there! I absolutely love this illustration! The composition is fantastic! :D You could improve the lighting even further to make everything stand out more. First: Make the background light more intense. This will help the characters stand out much more clearly because the “dark against light” contrast will become stronger, which also means you’ll likely want to darken the characters more. You can also play with warm vs. cool color relationships: Since the main light source is warm, everything in shadow can be painted with cooler tones. Additionally: Paint some light shapes along Doctor Octopus’s silhouette and tentacles. And speaking of the tentacles: Add a red light to the glowing sections of the pincers; this will create much stronger contrast and visual impact. Hope this helps! | Artwod Feedback
