I really like this transformation sequence (my favourite of CrystErMos, 3rd favourite overall of Usagi's), but there's quite a lot that I find strange/weird/lazy about it.
Going in chronological order:
• The effects for the moon bindi shot (for lack of a better term) could have been used to actually make it appear, instead just glimmer and shine.
• The blonde hair/energy body is looks cool, but it creates another aesthetical inconsistency in the series, the opposite of what we need.
• I don't understand why they couldn't just fully "complete" the glove instead of having it pulled off screen by an invisible force.
• There's an animation error with Usagi's feet where the silhouette of the boot appears prematurely (similar to Mars Planet Power, Make Up).
• What's the point of the ribbons going up the whole leg solely to make the boots knee-high.
• The red ribbons appear out of nowhere, when they should have materialized either with the wings or with the leotard and skirt.
• Seeing Usagi only wearing her gloves and boots feels like a bad attempt at fanservice. Previous transformations have the leotard appear first, most likely for that reason.
• The last zoom in on the face could have been used for the earrings and hair accessories instead of having the bindi shine uselessly once again.
