I did this image a while ago, and I am not sure what texturing I used on this. I do know it must have been several different ones combined, it looks like I did a push and pull with the history brush.
Back then that is what I used.
I see underneath one of the horses on the right side, you can see the cannon shooters and the smoke were not textured like the foreground. It looks like I should have textured that area which would have toned it down.
Too much detail there too close to the edge. I am sure I toned down the image using yellows and reds, those colors together look like sepia, then I bring back some of the original colors. Pushing and pulling again, pushing and pulling means that I put in a texture then erase a little where I do not want it, then add some textures back in. I call this push and pull. That term is also used in watercolor.
