Hi Madelyn, I'll try and provide some feedback for you. The color variation helps a lot in seeing the 3 different sections. - In general, I'm seeing the sternal, and abdominal parts not have a bulge towards the armpit. They don't feel like they have the correct volume. Proko mentions the bulge having most of the mass of the muscle. - In all but #2, the left arms are closer to the body, so they will squish the pecs more. Again, the volume in those feels flat. #4 is getting there, with some c-curves in there indicating volume. - #2 had the same mistake I made. The pecs can arc up more. The clavicular portion can go high enough to obscure the clavicle bone. And the lower 2 sections would mimic the rib cage's arc a bit, before turning up to their insertion, which will be a pretty foreshortened line. Good effort! And hope this helps!
