Cool! I thought it was good how you had the TARDIS appearing. The dalek voice was really good, and so was how you just generally edited all the voices together. The Opening titles being in the old style worked quite well. To improve one thing, if you have a shot of the Doctor walking out of the TARDIS again, I think it would probably look better if the Doctor was in front of the TARDIS- that way it would just look like perspective that the Doctor is bigger.
Thanks. I'll bear that in mind if I do another one in future.
