Saying development has been \'slow\' just because you see no new areas or models is a very ignorant.

You\'ll be pleased to know we have both 3D and 2D prospects which are shaping up to be very promising members of the team.
In the meantime, development has not slowed down; merely, focus has shifted to more \'important\' things than some new expansive, barren maps for you to run around and do absolutely nothing in. Maybe you want more of that, I dunno... but our artists are currently working on better things.
Your work isn\'t too bad, eye. I\'d suggest studying a bit to improve your anatomy/bone structure detail. Practice makes perfect, after all.

Once you have a decent collection of high quality work, I\'d suggest applying to the team, if that\'s what you want.
