opening shot idea

this is what i am intending to achieve for my opening shot. the idea being its a kids room with toys on the floor, the camera pans right and you see the toys scattered, and then come across the toy train set i will be making. the idea will be for the watcher to not realise that the train set is actually cgi. i created this shot in after effects and photoshop to help give me an idea of what it will look like and how long the shot should be.
