Apart from an evident colour change [Mike much prefered camo-based colours, I was on the fence, but eventually agreed that it will work out best], I've redesigned the guns. In particular, I made sure the guns cast a strong silhouette, in this case, a shape reminiscent of certain tank turrets. I have to bear in mind that the character will remain small ingame and so focusing on minor details yields little results in the long run [no pun intended, honest]. Only large shapes and patterns are recognizable once the character is shrunk onto a game screen.
In other news, more sketches :D !
