Lux and Nox, The Perstieg of Balance

To me, I must say that this really isn't your best artwork. No offense intended. First, why is the sword Nox is holding white (sorry if it was just in the design, it is apparently hard to critique requests without critiquing the original)? Shouldn't it be black or red? Also, to me the purple hand is a little large. On Nox's ear niche, the inside is blue, not black/gray. I'm not sure if that's intended or just a mistake. Also, the feet on both Lux and Nox are a bit off. On Lux's ear, the hair color bleeds into the ear and there is no actual line there. However, it is still a better art piece than I could make in a billion years. The clothing is fantastic, not a flaw in it. The effects are perfect. They really capture the light and darkness. I do know that this is a little unfair, as you did not draw the original.
