Everything is coming in sooo nicely! My couple comments -
I'm not sure how you want to do your side chest - I've always tried to avoid that twist & bend to keep the line across your shoulders straight. Also reduces the squish down on your abs -- up & high, chest out, rotate from the waist shows off a really nice lean waist. IMO anyway.
Rear poses - you said you were working on an alternative to the up on the toes poses -- I woudln't do the rear foot flat on the ground and I woudltn' do it straight back -- I'd put it out to the side & back - same idea as your front poses. I tried to find some good specific examples of this --- here's a couple --

-- look at the women's bb comparison pictures for rear lat & rear dbl bi
-- look at the ALL pictures - in the first 4 pages there are some nice rear poses to look at as well -- its a matter of finding a pose that looks elegant but also allows you to plant your feet well so you dont' tip over.
