Here's a few GIF animations. I only liked the fanny-flailing of Cirno, because that silly bubble-butt amused me, but I probably won't make the other moves into GIF animations, (unless people badly want specific ones).

Tenshi and her floating Keystone was also requested as a GIF, although it differs a lot from the one in the video. The hair, shide, clothing and pretty much all that waves and loops, was looping in different lengths. 28, 32 and 34 frames, so that sections of her hair would go off sync after a few runs.
This GIF was all reduced to 31 frame loops on everything, so it should all loop nicely.
I disabled the smoke trail from the fairies. Also thought about removing the fairies, to have it just be Tenshi alone, but I realized the hole where the fairies are in, was drawn directly on the Keystone and I reeeeally don't feel like doing any intrusive editing on any of the graphics at this point.

Some also wondered how I manage to make my animations, so I'm giving a brief round-up of my work process (although it's a bit more complicated that just this...), however, basically:

I don't just spew stuff on to the screen. Decent results have to be wrought out and worked for.
Since I'm a solo-Animator, I have the entire scene inside of my head already, so I usually do the entire soundtrack of the animation first;
getting music, sound effects timed right on cue, etc. Until the timing matches how I imagined it.

I then doodle out really crude sketches for each unique, significant events to visualize my ideas a bit better to the music and sounds.

Optionally, I do a little... what's it called? "Proof of Concept"? Where I draw and color a still very crude version, to get a better idea of the style and coloring I'm going for.

Then I flesh out the art-style, sketching the final style I want to use and begin animating the full thing in this manner.

And finally, color the whole thing, export it... then SLEEP! as I usually lose a lot of this in the process, LOL.

I overdo a lot of details, whether it's experimentation or for a further purpose. Few- or probably NONE who viewed my most recent animation noticed the small rainbow refraction on the rim of Daiyousei's shiny eyes. I went to study characters from old anime, that are well-know for their "yuri"/love-interest towards other female characters in the shows. Primarily their eyes, as I wanted to give Dai a bit of that vibe to live up to the silly fanon, of this otherwise unknown fairy; her having a secret/glaringly obvious crush on Cirno.
One important example, I took notice that the shine of her eyes, had a sort of rainbow-ish rim around them. I was unsure if this was intentional, or chromatic aberration in the (OLD) screenshot, but I liked the effect and decided to go with it or something similar to it.
