Being a panorama makes it a bit harder but if it was a single shot I'd try a fill flash (just forcing the camera to fire it off, if it's a mid-higher range P&S IIRC you should be able to adjust the flash strength as well) so you can get a little more detail out of the trailer. For the composition maybe move between the 2 in the middle? For the trailer that's the main focus in the middle we just the the back end and not much of the wheels, but in the current location it looks like you're lined up with the cannons so its not the easiest of calls on where to go. Is this location close to you? Because I see tons of possible shots, like looking down at those cannons with the 2 wheels on either side framing the image if you can get a focal length where that would work. You also have that tree and tombstone which you could try out different compositions using those to help frame the image. And just a cool shot looking down the barrel of the cannon, and using macro to focus just part way up it. P&S's have a pretty long depth of field but with the macro setting you probably can get it to blur out the background which could be a cool effect so the viewer is at the pov of someone aiming that cannon at who knows what and they can fill in the blanks. Something like that would be a good picture to mess around with filters and different processing techniques too. Trying to replicate an old photo isn't easy but you'll definitely learn a lot in the process.
