HMHM, much better shading on the butt peach! The apparent source of light doesn't match up, though; the specular highlight suggests a light source from the top right corner, the shading suggests one directly from the right, and the shadow suggests that Butt Peach (because let's face it, peaches look like butts) gets hit DIRECTLY in the face by the light, which by proxy almost seems to come from the viewer (though that would explain the Squint of Hardcoreness). You'll have to make up your mind, i'm afraid. :v
That besides, good to see you making progress, keep it up! c:
