I'm "faded" for the first time in a while, so I have a few suggestions if I may...
1) I'm not saying to abandon the Montezuma-based-Nebuchadnezzar, but I think a slight overhaul might be in order here. First of all, it is clear and obvious that the LH is based on Montezuma. Everything is the same; his eyes, his animations, etc. Not to mention the similarities with the last version of Nebuchadnezzar. I think we can "fake" enough of a difference by simply changing his eye-color, skin-tone, hair, beard, and *SLIGHTLY* modifying his nose.
2) I think this LH can do very well with a nice background. So far the Nebuchadnezzars of the past have had simple screen-shots of the Hanging Gardens wondersplash. I think we can do better. I have a few on my computer I'll post in a different post to make it easier to identify. But backgrounds are important because they are often overlooked.
3) I think you should break away from the common-conception. This is something I tried to do with my new Aborigine (Yagan) LH. I took the same basic concept (a shirtless Gandhi) and put my own spin on it. You should really try to do that this time around, considering it is the third ideration of a leader that was written about in multiple historic accounts, including those of the Babylonians (obviously), Hebrews, Egyptians and Greeks. This is a supremely important leader and you should think about that when creating him.
Anyway, I'll put up some ideas for backgrounds too.
