Hi hi! Lovely scene! I like the dynamic between characters! Let's start from the beginning. When we have our linework done, we set our flats for shading in layers under linework. When picking flat colors, make sure they are not too dark,too bright or too saturated. You want to have them somewhere in the middle,otherwise things get muddy quickly! After that, we determine our light source. Here I change so it comes a bit more on top and less on the bottom side. Depending on what type of mood you want to present,we pick our main light. Arrange the shadows with multiple layer, match the core shadow to the character elements, and use a neutral color for the shadows (typically warm for cool light and cold for warm light). Here you can go with bit colder shadow since the sun is coming down (but not 100% blue,just a tint of blue). Have in mind how you shape the shadow: they have to follow construction you had with linework. We break down to simple forms (spheres, cylinders, triangles, and squares) when approaching placement with shadows. For now, you can keep iit simple until you get a solid understanding of how cell shading works. Later on you can move on more challenging tasks like adding more values, defining human figure better etc. Hope it helps! Happy learning! | Artwod Feedback
