Great studies there! Glad to see them!
I think the figure positionings are nice, most of them are anatomy book worthy. Also, the pear is nice, but I like the Pear a bit more. I think that the pear is a bit too spongy...maybe that's what it looked like, but I think the apple, because it's a bit smoother, is more successful. I also think the stumbling of the stem, it doesn't connect correctly to the pear, at least visually in the picture. But, I should move on and stop talking about the pear...I'm sounding like one of my friends that will grab on to one thing and critique it over and over and over again.
Anyways, lookin' good, but post more!
