Very cool effect!
However, TBH, it didn't strike a cord with me.
Not sure I can describe why, but I'll try... The equal sized and brightness swirling dots coalescing in was rather disconcerting. The bright actinic light source is also a little too strong and regular, IMO. Also, the encompassing pattern feels too distinct. The moment just before disappearing, the blue blurred and expanding effect with the electrified ice pattern, however, really was striking - if the ship took on the bright expanding light that suddenly extinguishes, that would be sweet.
Not to sound too critical, though - its a very nice creation and thanks for sharing it!
