Hi,
I found it really fun today trying to see an overall shape created by an instant of movement. Example the arch created from the head to a trailing toe. Or a triangular shape created from two legs in stride. Hope these drawings i made are helpful for you.
Some other random things that i found really helpful were using low opacity on brush because it allowed to empahsize areas of pose by just drawing over area more. Using a a little tone for areas of sketch. Saving pages to separate psd files to have a cleaner working environment.
Happy Sketching!
Nate

Aaron Blaise (creatureartteacher dot com) I learned a ton from watching his online youtube videos on capturing gesture then later using that to build anatomy on top of it.
