8) You're good at painting

Great effort, not to mention an awesome user name!

Your models are looking really great. I would recommend you look in to using some inks. Black ink on the silver armour (followed by a final and very "dry" drybrush of silver).
A bit of brown ink on the red skin before the final highlight, and watered down brown ink on normal skin.
Brown ink on the Gold armour as well, and again you can give a very dry dry brush of pure gold afterwards.
Because the ink runs in to the cracks you'll get a much better definition on the detail, and higher contrast between light and dark.

For other primary colours use the same colour in ink- blue over blue, green over green, etc. If that's not dark enough go in with a smaller amount of green darkened with brown or even a spot of black (but only a small spot), and place it only in the deepest recesses of the model's detail.

Hope that helps a bit. Keep up the good work!

Your men of Numenor are very good, and Lurtz. I don't think you're capturing the shine on the elven armour. Try a brown wash and then highlight the edges of the scales in bright gold.
