Ok, ok.

Here is your ridley side view (crappy example).

What you're doing is on the left, you're shading it like the light is the same all around. That just doesn't happen, even if it's the sun we're talking about.

The one assumes that it is the sun and it's directly above it. The shading still wouldn't be pillowed because light doesn't hit the object completely parallel.

EDIT:
Really, guys, I think you're just flaunting terms. Don't assume everyone knows what contrast and hue shift is, explain it to them. If they're a new guy, most probably they wouldn't know that.
