By no means am I saying this dio is bad, I'm am just saying stuff to make it more realistic.
The bad:
The tents:
Sorry man, they (the small ones) need something to hold them up. I've slept in one and they have two poles on the end usually sticking through a grommet. They also look way too rigid like cardboard. I know canvas can be strung tight but youd have two have a super-rebel for something like that! Also there are stakes that hold the sides out to make more space and keep the rain from flowing in. One last thing is that most tents wouldn't be painted with a CSA. Paint was valuable and the south wouldn't waste it on labeling small tents.
Ok, the big tent: This looks good (And I'm assuming this is 1/35) but it seriously needs some front flaps. This might be the one thing to let the CSA thing slide on, it's habitant might have been a little arrogant and didn't mind them new-fangled "balloons" flying around
You can easily find pics to help you on the internet with the tents.
The Good:
The Flag: Dude, this looks great. Especially that you have it flapping in the wind. It adds more realism.
The wagon: Really good job on this. The only thing I can say that is bad is that you need some wooden supprot beams to show through as the canvas didn't magically float.
The Cannon: That's amzing too. good job.
The groundwork: Looks good.
I am in no way trying to bash you, I'm just giving you some advice that will make it more realistic. Maybe you can also add some personal gear in the tents to really draw some attention to it.

BTW: Reason I really want to help you with this is that I have a big interest in the civil war too. My heart says Dixie but my mind says Union
