not meaning to be negative , you obviously are quite advanced in your modeling skills and are pushing the envelope on figure developement , however i have circled a couple of areas that would cause me concern in making morph targets for this figure, i see you have made extra geometry in some areas that are often used by modelers for making custom figures...this is good.... but edge flow is critical , i see disruptions in flow in the areas circled and IMHO you went a tad overboard on topology in these areas, if these areas were cleaned up a bit  before rigging i think the figure would be more workable thus making him/her more attractive/useable to the end user... this is just a suggestion im not meaning to hurt anyones feelings or critisize your judgement, only trying to help ...

:O)

Y'all have a great day.
