Looks nice! (though I would edit out the one black frame between shots about halfway through.)
As for myself, despite being an animator, I haven't made any sort of animate promo material for Trespasser.
Kinda takes more effort to make than the results it would bring in. Besides, I feel like if I were to make specific animations for Trespasser, purely for promotional purposes, it would take away from the comic.
That said, I have in the past made small videos, usually process videos.
I do have this one Blip animation that I made before I applied for a motion design position, to re-familiarize myself with After Effects. It's pretty simple and didn't take me long to make, but it's kinda cute in a way
(EDIT: okay so the forums did not like my link to the instagram version, so I had to upload it to youtube to actually show it.)
