BrettG's Sprites and Pixel Art

[BrettG]

Alright so I scrapped the previous colour scheme for something a bit more military.
also reworked the details and pose as the original looked very awkward after isolating the linework and have attempted to add some more depth to helmet and lower body.
Went an AA'd some the lines of the gun to get rid of that rough look as Faeldspr wrote about.
Thanks for the crit so far!
