There's no "butts" about it.

I got started off with the gluteus minimus and medius. It was hard to place these two at first since parts of them are buried under the gluteus maximus. But once I got them in place, it was easy to see how this muscle group has so much volume to it. The IT band and gluteus maximus were equally hard to place on the mannequin. I used the muscle poster in the lab a lot to figure it out. I enjoyed working with these larger muscles. I've had some difficulty drawing all the mass and musculature around the pelvis, and after sketching my model a few times, I've gotten a much better understanding of where to place each muscle. Its become easier to pinpoint some of the landmarks on the live model when drawing.

Ryan- Seperate the longissimus, and try to make it a bit thinner, as it is one uniform band, rather than a flat sheet like you have it now. Try to round out some of the spinal erector muscles, either by trimming the edges, or by adding little leech-like bands, and smoothing them out around the form. You could probably go without some of the minute details of the muscle fibers and strands because it tends to flatten the forms as we view them. It might be more beneficial to just be viewing the structure of the muscles, and to imagine the strands and fibers are there.

Mark- Try to use your tools to clean up the forms, and round them out so we can clearly observe where they meet and how they relate. The muscles in the upper neck get a bit bulky. Try to imagine skin over some of these areas and how they would be protruding and how you can make it seem to be one structure consisting of several forms, rather than a bunch of different objects. Take a good look at Amy's model and some reference material, and observe the proportions and relationships especially in these very complex and difficult areas like the spinal erector set.

General Note- The spinal erectors will now be referred to as the erector set...

Jake- You should thin the muscles out in the thigh and lower back in some of the areas where it seems to get a bit bulky. The external oblique should meet the ribcage, and the abs should meet the obliques in a more gentle and less geometric and clumsy fashion.
