Hello hello! That is some badass looking penguin. They are quite menacing little creatures! Using basic forms (spheres, cubes, and cylinders), defining shape using cross-contour lines, and defining shape with consistent shading (highlights, midtones, and shadows) are all ways to achieve that three-dimensional volume with any form. Because you tackled blocking values on creatures, I brought up adding shadows here. Along with making simple forms, it can be an enjoyable exercise. Once you are happy with the linework, you may utilize shading to create textures on the surface. Make sure you use as many layers as necessary and proceed step-by-step. after experimenting with many patterns and ideas! Enjoy interacting with other animals. Check out Artwod tutorials and try out their exercises to learn about creating forms in 3D volumes from various angles! Hope it helps! | Artwod Feedback
