I really like this model. Your NMM is very nice, the light placement is well done, giving it that realistic look. The areas I think that could be improved upon in my personal opinion are; mind you I'm trying to be harsh here, as I know you like me are trying to push yourself.
* The shadows in some area could be taken further, there seems to be a lot of mid tone, some good highlights but not enough shadow for contrast.
* Colour theory; with the blue based NMM, I don't think choosing blue for the cloak is optimal. Using a warmer, red brown - red colour would have been a better choice I think, complementary colours are your friend, bring out even more contrast.
* The eyes look like they could be neatened up a little more but are good, especially the reflection points.
* The blending, although nicely done in most parts is not consistent in it's smoothness. Contrast the sword hilt with some of the metal areas of the armor and you can see a visible difference in the blending - I do like the bit of green you added on the pommel, nicely done.
* Also start to think of the different types of contrast, they range not only in light and dark, but from warm to cold, textures etc.
To push it further you could give the lower part of his armor a very light glaze of green to reflect the colours of the grass etc.
Over all I liked watching this miniature come along and progress - well done impo your best mini yet. Gets an 8.5 from me, if the contrast and colour theory were pushed further it'd be a 9.
