The game “Halcaua” appeared in sec. XVI in Moldova and Valahia. It was a game made for Knights. The word "halca" means in turkish a steel ring. The purpose of the game was to ride in speed towards a tree and pick up the ring which was hanging there. Bogdan, son of King Alexandru Lapusneanu was one of the famous player of the year 1568. And then Dimitrie, son of King Cantemir.

I used “Zvezda 8036 French Knights XV AD”, 1:72 scale.

I like the red figure, you've captured the drama well.
I like the shape of the tree, I would add a bit more 'volume' to the leaves near the ends of the branches to make them bushier.
