Hi! Honestly these look very good, but if you struggle with the concept you can try using a notan method without any blending to get the hang of it. I always put small details right away, and only recently i've had the discipline to avoid this, and the progress is amazing! Grouping lights and shadows at the start gives you a clearer readability, so please try! I did a quick visual feedback to further explain how i'd do it, sorry for the butchering of the beautiful derpy cat! | Artwod Feedback
