Since my last post, I worked to finish off the column. I focused on the front side first before turning to the back.
I also took care of the sign on the front of the column. I applied a few subtle shades of dark grey to the gate to give it a little variation (though nothing major). Then I added a bit of grass and some dead leaves to break up the ground work. A few pigments here and there on the ground and base of the column, and the scene was complete!
The final step was the add the sword and scabbard for the dragoon. The scabbard was painted in black, like the boots, and metallics for the fittings. The cloth bit wrapped around the handle was done just like the yellow-gold details on the uniform.
Here's how the final result looked. All in all, a fun project and one I'm happy with.
