I'm just noticing the shadow of the hand on the jacket of the man holding the spear. What an interesting detail to add! I don't know if anyone would have noticed that not being there. I also notice the perfect use of color on the blue tassel of the spear- how did he get the shade of paint in the light and dark parts of the tassel so exactly correct? It's almost like this was drawn from a photograph- but that can't be. I wonder if he had live models standing in to draw from?
Also, I notice that the boots they are wearing actually look very practical- they're shoes when you need shoes, and long boots when you need boots. What a good idea.
