prepping a new portfolio for 2013/2014

trying to get ready for portfolio in 2013- need to upgrade my storyboarding skills to match up with advertising agencies  for 2014 so i am trying to upgrade my portrait skills- here is my first try

what I need to do to improve by my initial assessment

1. work on my draftsmanship on copying gestures and portraits- the image is too messy

2. work on my selections for more refined coloring layout

3. work on finishing touches and highlights more effectively
