I'm not up to date on the first two parts - there's a really great 80s feel to it, which I hugely approve of!! Not just in the gorgeous incidentals, but also the large amount of TARDIS action, and the references to companions' rooms plus the perpetual background hum - spot on, it's very easy to picture this taking place inside the TARDIS. Not to mention the Cyber voices, how on earth did you manage to get the effect of that so accurate?
