1 and 3 look great, 2's perspective draws too much attention to the faces, where the shading is actually too aggressive. The way it is now sets the faces too apart from the rest of the body making them look detached, and this is enhanced by the perspective. At 2's bottom panel, this effect makes the characters, specially Nitori, look flat.
So the shading looks great, but it isn't the right kind of shading for the perspective.
