Is the shading correct?

[tall egret]

I tried to shade this guy but somehow seems a bit incorrect,, anyone can help me fix?

[mossy briar]

the Shading on the head, theres a shadow that would cover his hat and maybe half his head

not just his face

[dense patio]

So there are inconsistencies in how the shadows are formed. Especially the cast shadow on the grass. How cast shadows work is that the shorter an object is, the shorter the shadow is. In this case there’s different parts that are taller and need a taller shadow, meanwhile also shorter parts that need a shorter shadow. Really pay attention to how tall it is and change the length of the shadow based on that. Theres also parts that seem like that you aren’t fully thinking about where the light is coming from. Pick a direction and try and keep the cast shadows parallel to that direction
