Above is the whole scene. The good weather let me set up in the garden. I think the trees look quite effective. The fences help to frame the scene and make more difference than you might think.
Here is Cornwallis's map table. The maps were made by reducing imaged of real maps of the period (thanks, Google) down to a suitable size - approx 2x3cm using a 1000 pixels per inch resolution.
Above, the 17th LD gallop out, past the commissary tent at the back and the surgeon's tent in the foreground - note the stretchers, these come as part of the bell-tent pack from Renedra along with the camp fire that you can see next to the map table.
Another shot of the gallop above, the trees making an effective background.
I have used plenty of sacks and barrels from Hovels with extra barrels from Renedra to add some atmosphere to the camp, while keeping it quite generic so it can be used for either side, or even in other periods.
