My bfs Fursona

Hi! That is a cute design! I think the shading looks off because parts of the drawing are rendered with different light sources in mind - her body is shaded as if light comes from top left, but paw drops no such shadow and is shaded as if light comes from front. Hair is shaded as if light comes from the right. When doing shading, decided on one light source and then try to render everything with that light source in mind. Try to think in 3D. The environment around the character is yellow/orange - it should affect the color of the character as well. I made the hue more warm to match the background. You also pick all too saturated values for shadows. Usually shadows are not just darker but also less saturated (and have different hue) than the main color and vice versa (unless you got for a specific style). You didn't ask for feedback for it, but I would invest some time into the topic of line quality and line weight. I think it would help you to push your drawings further.
