[Disclaimer: programmer opinion, beware of using π ]
The animation looks nice overall!
At closer look I would say that the side-facing parts (the red parts in the image below) move too far left and right, since from shading they appear to be at a 45 degree angle but move in and out as if they were at flat 0 degrees when viewed more from the front and 30 degrees when viewed partly from the side.
Sorry to add that as well: In terms of glow you could also add a camera bloom effect instead of / in addition to particles.
