This is absolutely excellent. YouTube user The Confession Dial has incorporated the last moments of the Big Finish audio The Last Adventure (very much worth listening to) to footage from The Trial of a Time Lord, Time and the Rani and more to create a new regeneration scene for Colin Baker's Sixth Doctor. It's almost a shame that the lunacy of Time and the Rani has to follow it.
Spoilers for said audio adventure, of course, but there's far more to it than just the regeneration. I’d recommend listening to The Last Adventure if you haven’t. Although I imagined the Sixth Doctor looking closer to how Colin Baker looks now (after all, we saw in The Time of the Doctor that a Time Lord can revert to a youthful state just before regeneration completes).
Apropos of nothing, I now have a Tumblr. I tumbl.
