I know A is Pillowshaded, but there's certain things in A I like (Princess, Ladder, Grass (not the platform the princess is on), Dragon).
I know B is correctly shaded, but they definitely did a ****tier job in almost everything. The tree looks way worse, where's the leaves? The dragon doesn't even have its scales anymore, they used way too much contrast between shades, so on and so forth.
I'm assuming this was supposed to be a respresentation that pillow shading can look better than actual light sources at times. But in all actuality, they purposely limited the details in B to prove that point. If they had included such details that they did in A (tree leaves, grass details, dragon scales), it'd look better than A.
Tbh I like A more, but only because I'm sure whoever made this wants me to like A more. If B had been finished (or even looked remotely finished) I know it'd look a lot better.
