Great job as always. Very enjoyable. Extra tips: You may use the Target parameter to further scale up the images, if you like... and maybe place them off screen at the first keyframe. Also, if you're not fond of the sliders to change values, there are buttons on the right of the Effect Editor Window which you can enable for some parameters. One of them is for Crop and you can then do this just by grabbing the the handles right in the effect editor window.
