Basically, if you want to take something like that you have to take the finished artwork into your 3D package and camera match it as closely as possible. This is more difficult with purely organic scenes that have no real straight lines, but you can also be slightly more free with perspective when this is the case too, just get as close as you can and make sure you have the horizon line spot on. Then you need to model all the elements in the right places, which can be quite time consuming (it can look great from the cameras point of view but be a mess from another angle). Then you need to project the painting back onto the geometry.
Its usually a good idea to do that in layers as you can paint in behind the objects to allow for more parallax. What you may still find tho is that you have to patch up the projection, i.e. reproject bits of painting from a different angle to cover an area that is revealed in the camera move that the original projection doesnt cover.
Take a look at the Gnomon dvds on matte painting and camera mapping, it might help you out if you havent already seen them.
