1) Copy and paste the image onto a new alpha channel
2) Make a layer and fill it with red
3) Make a layer and fill it with blue
4) Load the alpha channel as a selection and create a layer mask for the blue layer(You may need to invert the layer mask)

Remove the lens vignetting first then stabilize the footage. Then add a new one back in.

You have to give the rod a start angle that is in line with the axle, i.e. the other (loose) end of the rod needs to be vertically where the center of the wheel is.

Puppet Overlap tool
Use this tool to place Overlap pins, which indicate which parts of an image should appear in front of others when distortion causes parts of the image to overlap one another.

Rather than duplicating your comp 10 times, you can add a Curves effect and curve the alpha channel to get the right level of opaqueness.

Don’t know of a tutorial on this, but here’s a dummy file with the technique.
Basically I used two additional copies of the keyed footage, filled with black, both with the same mask one set to add one to subtract.
Make the two shadow layers 3D layers, then put the anchor points at the mask’s edge and rotate the bottom one to be horizontal. Because the anchor point is at the fold, you can then stretch the bottom part depending on how long a shadow you want by scaling it on the y axis. Then it is a matter of making the camera angle match the perspective of the shot, which you can do manually (Temporary grid effect helps).

For circular motion, you don’t need a path nor expressions, you can put a null in the center of the circle with the other objects parented to it. Rotating the null will rotate the objects in a circle.

The artboard size doesn’t really matter — as long as it is larger that the artwork — rather the size of the artwork itself. But if you want to be on the safe side, make the artboard that size (19.35cm x 19.35 cm) as well. The main thing to ensure is that the artwork itself isn’t larger than that. I’d say it would be simplest to make the artboard the same size, then you can easily see if your artwork fits inside it.
In such a case I usually make the artboard the smallest US or international paper size that accommodates the artwork (such as letter size or A4), depending on where the customer is based. This obviously applies only in those situations where the paper size has no bearing on the trimming of the final product.

Easiest fix I can think of is to include everything inside the mouth including the dark red inside color in the objects being masked by your clipping mask. By this I mean: make a larger area than your clipping mask for that dark red fill and then crop the whole lot (all four objects that make up the mouth) with a single clipping mask to the final mouth shape. That way you won’t have the two separate layers’ antialiasing creating an edge-like artifact.

A number of ways to do that, yes. I’ve done it with displacement mapping, with camera projection and by mapping the lower section of the shadow on one layer and top part on another layer. For a more organic background you can use mesh warp. Not sure what is the best one for you, I guess the one that seems easiest.
