Hah, stumbled upon this.
Well, this piece is pretty calm and ambient, for the subject in the description.
The bells at the start were a good intro to step into the music and imagine, the sounds of the cannons (If I'm certain they are cannons) were easily helpful in imaging the tune in a scene.
No sound difficulties or big improvements needed, but I'd say it is good as it is. BUT, if you are planning on maybe remaking this piece, try adding more power to it, maybe a little more instruments and more things to make it a bit louder and more "dramatic" in a way. But if you're not, it isn't necessary that you do so.
Anyways, the things that has been shown to me through this is actually quite good : The soldier leaving the church seeing at the horizon, a battle has commenced. The sun shines brighter than any other day that the figure has seen. He spots a barrage of cannon fire raining down from the sky coming from the opposite direction. But he pushes forward. The view switches and goes through the battle, seeing the good side reigning victorious, raising their banner upward in the sky as the evil retreats back to their corner. The fighters raise their arms in celebration, only to see their fallen comrades lay cold on the battlefield and knowing there is much more to be done and that, there is yet another battle that is to come.
