On GLaDOS’ Flickr page you will see a number of very good painted custom minifigures however the one that really stood-out for me is this Forest Sniper. He features a Modern Combat Helmet from BrickArms along with a tactical vest and backpack.
The black, tan and brown painted camouflage really stands-out on the green background and looks great.
The camouflage head works really well, and he comes with black boots and a sniper rifle that also has painted camouflage.
Overall a very nice combat custom minifigure, and the choice of background makes a great showcase photograph!
