Week 5 - Life Drawing - Proportions

Very similar to the directed study on the same topic for the 1st semester, I drew both male and female characters in side and back view(and the male in front view) according to the idealistic proportions.
The 1st sketch seems to be off, mostly because the marks for a head unit along the body are smaller than the head actually is. This makes for an unnatural feel for the whole character. Also, there is kissing along the entire edge between the arm and the body on the left side of the sketch. In addition, the musculature on the inside of the legs seems completely overlooked - there is a simple straight line separating the legs. In overall - bad proportions and bad composition.
The rest of the sketches have generally good proportions, with the hips at the middle of the characters, the waist at one head unit above the hips, the shoulders beginning at 1/2 head units under the chin and reaching  the widest section of the body at 1 head unit under the chin. Also, the knees are just above the middle of the legs and the width seems correct with 2 head units for the female and 2 and a half units for the male. The muscles seem to be defined a bit better, except for between the legs in the front view drawings and the front of the female's hips in the side drawing.
I have to note I really like the way the shoulders are shaped in the side drawings. Unlike the ones I had in the sketches in the 1st semester, these actually show a smoother transition from the thinner part at the very end of the shoulders towards the chest where the body is thicker. Still, the male ones might need to be just a tiny bit wider, so that there is an even smaller difference between the front of the shoulders and the male's breasts when looked from the side.
