Thanks fellows! He's the recently-released "Gallant Knight" from CMON.
The backstory (from long ago) for the Mage Knight figure I'm using him for, had the character as an adventurer sworn to service to some dragonfolk, now roaming the land to help those in need.
He was a bit more of a cheerful fellow in the fiction that came out to support the sets he was in, but the figure is a bit more stoic so that's the way I wound up painting him. I tried to bridge that by giving him a brighter, more colourful costume. So perhaps this is "a serious moment", but he's not grim. Either way, the relaxed confidence is perfect for a warrior trained by powerful magical (dragon) warrior monks.
