I think he's looking great. The sheild is super!
As for the skintones, I don't think its too pale, but rather look 'not finished'. Im sure it looks different in person, but on my screen it looks like it has very little contrast. All you would have to do to 'bring it to life' is some well placed shadows, and it would look a lot better IMHO, and make him look little more seasoned.
Keep up the great work and shoe us your progress!
