The skeletons look GREAT. Bold and simple, I'm sure I'm not the only newcommer that would love a tutorial of these. They are really great. The necro Adds a lot to the regiment as a whole, but the blending could be a little better.
Think about the tutorial, they are truly that great!
My old favourites, these skeletons aregreat and have a good coordinated look to them. The necromancer looks good as well.
It may be you photo but if not then I would just dull down the metallics a bit and also the bone could be toned down a touch as the are just rising out of the earth.
Great job nonetheless.
