Look at my horse, my horse is amazing
First we were treated by cosplayer Kelly Jean's amazing Quiet recreation that was so good you had to do a double take to see which one was the real image. Now continuing the Metal Gear Solid V cosplay goodness is RBF, taking cosplay to the next level by riding an actual horse. His face is also highly detailed with all the battle wounds we see Snake suffering from in that amazing E3 trailer.
RBF's deviantART page is filled with loads of good cosplay, ranging from more Snake's appearance through his various titles, to his impressive Assassin's Creed IV's Kenway.
