As a rule, I don't comment on people's art, I never feel like I can say the right words but this time...wow. I can not even begin to express how amazing this is. I was looking for inspiration for a dragon in my novel and when I saw yours, I died a little inside because nothing in my imagination even comes close to this. Amazing, amazing work.
The use of strong silhouettes and mist-setting-back (layering), that held to give a sense of large scale, too much detail on something that is far away doesn't look write and anyone brain can spot this. I guess that the horns aid flight control for sudden movements too, and could be light weight with honeycombed structure. His ragged wing looks like he's been in a few fights, maybe the horns are for sexual display also, fighting with other males? however he has a relatively slender neck so I don't think it would be for actual combat.
It's the shape of the head, in pitch black the predators had wide boomerang heads that help them sense in the dark where the prey is. I imagine its like a hammerhead shark that has sensors at either end of the hammer that detect bio-electrical signals of muscle movements, and the difference allows the predator to hone in.
I'm honestly surprised this hasn't got more comments, this is a lovely piece! The dragon design is fantastic and unique, especially on the head. They somewhat remind me of hammerhead sharks, so very efficient predators, which is just further emphasised by the prey in the talons.
The lighting and shading is just fantastic, I really like the red tones on the dragon which keeps it from the danger from looking a bit too washed-out with the pale colouring. The subtle texture on the dragon also helps this
