My First Animated GIFs Involving Vehicles

Here's some early experiments I did with animated GIFs, involving vehicles. It's obvious that the backgrounds move in some of these. It creates the illusion that the vehicles are moving when they aren't. 

This is my first animation involving a helicopter. Nothing moving but the propeller here. 

I started to experiment on how to create a spinning propeller--facing this direction. It turns out that I just need a line that's getting longer and shorter to create that illusion. I added moving backgrounds for an extra effect.

I decided to try it moving background with airplanes. One's an airplane and the other is a fighter jet. It's obvious that I'm no professional artist. 

Here's one involving a car moving. Actually, it's the background that's moving instead of the car.

Once again, I wish Affinity Photo will be able to add an animation feature in a future version. Of course, that will cost additional money.
