always happy to see a lurker bite the bullet and start working on and showing some art themselves...and especially happy to hear that we can provide a pipeline of peer help and review to people who don't otherwise have access to it....that is a big part of what we are for and why I personally think this place is important.
buuuuut leave the back-story for 'Introduce Yourself'
http://entervoid.com/index.php?topic=4936.0 ...show more art in art thread....and NEVER ask anyone on the internet to criticize your life
based on just what you have here.......I would take what appears to be a strong enough grasp on anatomy, gesture and underlying forms and focus on line quality, inking and backgrounds....maybe even just cleaning up your sketches and doing some finished drawings to start
and just cut loose and sketch/practice everyday or as much as possible as you already have planned
continue to post your work and if you want specific help, elaboration and even just basic comments from anyone past what you already receive.... just ask...people around here will give what help they can
