Iron

Whenever possible, I like to look through a Lair's collection of coli dragons, as I feel it reflects the effort a user puts into their dragons, especially with an excellent unified theme like yours have! Iron is such an excellent tundra, I love the blue tones of tarnish, especially how they are used to bring out the cooler tones of his armor. Speaking of which, your apparel layering is excellent, and I love the blend of sets in his outfit!

Really love how this outfit is so complicated, yet not cluttered. Genes work together well, and the posing/colors/layers fit together SO well!

Iron coming right up!
I picked another earthy, brown dragon, who would've though?
Iron is one guard I wouldn't want to mess with.
You really added a lot of shields and other weaponry.
I'm sure that your other dragons must feel very safe in your lair.
That Arena scene fits so perfectly in terms of colors and motif.
All of your dragons have so much personality, I love it.

What a wonderful, down to earth guy. I'd certainly trust him with my life. All the apparel layer perfectly and give Iron the air of a quiet protector. That tarnish hex makes his fur look amazing and helps tie in those blue toned bits in his gear nicely without them standing out in such big contrast.

This boy surprised me. I was honestly not expecting to like him. Giraffe and Hex are, more often than not, a miss for me. But something about him made me keep coming back for this guy. And I think I've figured out what it is. I usually expect those two genes to be pretty one dimensional but the way you've dressed in the Heraldic apparel has created a nice gradient that makes him pop in a very unconventional and surprising way. He's unique. The Valkyrie blade was also a nice touch and works well with the Giraffe Tarnish.

If there's something I love, those are tough-looking tundras. They are all, ultimately, precious floofballs but this one really tries with all that (wonderfully layered by the way) armor. The outfit is my favorite part! You took bunch of items from different sets and made a wonderful mélange of perfectly-matched apparel. I also like the patterns on his mane a lot for some reason. Those are simply fun, I suppose.

Hmmm, lore. Glad to see that he's a good guy (dragons of his profession often end up being ornery and stiffening, as some of his companions are). He gives me a Shakespearean comedy character vibe. Or a Pratchett's Night Watch vibe. Both are great vibes, so I love him.

Last but not least: Iron. I love his blue & brown colour scheme (Tarnish is one of my most favourite tones and you emphasized its nuances in such a great way), the cohesive warrior design, and the stunning outfit. You're surely a master of apparel layering, and Iron shows why male pose Tundras can be absolutely glorious!
