I really like the composition of the scene, especially how you can see the path leading into the village in the background. Additionally, the way you made the landscape get slightly lighter with distance is a subtle detail that makes a great impact!
What initially drew me to this piece was the pose of the warrior. The anatomy is spot on, I think, which is very impressive considering that I think this perspective and the warrior's pose are both rather rare.
What I do notice is that the shading/painting style of the warrior seems to alternate between "soft shading" and "textured shading" (I just made up those terms to describe what I'm thinking). For instance, the hands are both done very well! You can see the texture of his veins and some nice shading is incorporated there. Then I think you switch to a smoother, more "cartoon-like" shading for his back and for his clothing. I don't think this is bad, I just feel like it might be a tiny bit inconsistent. His clothing looks very soft and not as textured as I would expect. That might be what you wanted for this piece, it was just my observation.
The landscape and all of the details around the warrior are very nice, I think! The only minor things I pointed out are what I think could be improved. Overall, I think you did a good job, so keep up the good work!
King Egona Kilburn, ruler of the Celtic Confederacy, champion of the gods, and savior of his people during the time of the deign food, felt weak as he surveyed the destruction him and his army brought upon this tinny Greek farming village. These people has no chance against his warriors, they were farmers not fighters yet despite that they refused to surrender to him a quarter of their food supplies. He pleaded with the leaders to listen to reason and not force him to take it all by force, yet those stuck up Greeks called him an unkept barbarian and refused to even consider the idea that they could lose to his horde. After all they were Greeks, the greatest people ever, and he and his people were not.
So after those useless talks Egona returned to him camp only to lead the assault on the village. The Greeks tried to defend their homes but it was no use, the Celtic iron weapons and the skill of their warriors far out classed the bronze weapons used by the Greek farmers. What happen could not be called a battle, instead it was a slaughter.
The Greeks got so desperate they tried lighting fire to their own homes in hopes that at least the Celts would not be able to loot their houses. But it wasn't enough and the Celts were able to get the majority of the precious food out of the houses before they consumed by the blaze.
Now that same food was being carted off back to their own homes and starving families as the surviving Greeks ran for their lives. And King Egona Kilburn slummed to his knees on a hill top over looking the village and while the ragging fire over ran what remain of the settlement, he fell to his knees, placed one hand on the ground and the other on his sword and prayed that he would never have to do this again.
But it was wasteful pray, the food here was no were near enough to feed his people who were staving do to the famine. Not a single tribe in the confederacy had food to spare, everything from the fields to the trees laid bare and lifeless. Then there were the Greeks with their fat cows and plentiful farms. Their was no choice in the matter, Egona had to attack them, it was ether a few thousand dead from war or hounders of thousands dead from starvation.
Yet no matter how much he tried to rationalize it, Egona could not forgive himself for the destruction he had brought upon this land and it's people. And this was only the beginning, soon his army would face against the great city states like Sparta, Athens, and even the mighty Amazons and they would all fall. They claimed to be the most advance people the world has ever known, but they used bronze, not steel, had no faith in calvary or archers, and their battle formations were stiff and inflexible.
So King Egona, the first Kilburn Warrior, ignored the pain of guilt and regret coming from his chest, picked up his sword, and returned to his officer tent were his generals and advisers waited for him.
