It's a great mini with a great paint-job but, it has to be said, that your first attempt at NMM, whilst creditable, has not completely nailed the technique. You shouldn't use any yellow in NMM gold. Shades of brown are the way ahead. Plus, you need more dark shading to emphasize the illuminated parts. Still, you've clearly got the core skills, so with some more practice, I'm certain you'll nail it!
