Yeah, the NMM looks great but it isn't perfectly right.
First, it needs more white at the upper edges (explained in chrispy's article: my thoughts about NMM. It says that white is most important! Aww just read it). Especially for the armour(if it's NMM gold and not just bone yellow.
And second, most importantly, the swords has 2 cutting edges (lets call them facets) And each facet reflects the reality differently, so if you look in the lower facet and trace your eyeline into the facet and use the law of mirrors(degree of income is degree of reflection) it points into the ground, so, it reflects the ground and not he sky, cos' it cannot "see" the sky. And if you o the same with the upper facet, you'll see that he can only "see" the sky. Hope this helps and keep up the good work (no, really?!).
