Hi!
From what I can make out, the Hummel looks pretty nice- I concur with the previous note on the net- if you prop it up over that gun and spread it out across the whole vehicle, you'll actually capture much of the ambience, I think. I'm really eager to see how that interior looks. A few good pics and we'll better see your nice effort!
A suggestion about the camera, if I may:
It probably has a "macro" button on its mode dial or selector or... This macro function should be an easy push-button feature and is typically marked with a small stylized "flower" - like icon.
Use the macro function if you want to take some pics from near to your model ("near" being less than a couple-3 feet- the typical auto-focus cannot "see" or focus the camera closer than maybe 3 feet in most cases. The macro feature will allow you to get the camera to within maybe 3 - 6 inches of the beast.)
You can also get great pics of a model by standing back maybe 4 feet or so and using the telephoto zoom feature. Simply set the camera on the "auto" function and stand back and zoom in! This approach will give you better and deeper "depth-of-field" in many cases, and is often the easy route- specially so for outside settings like you have used.
Nice Hummel from what I see and hope to see some new pics soon!
