Bit of a ramble I'm afraid, but as an Englishwoman, well, ...squee.
What an extremely well done 6th doctor cosplay. You have it down perfectly! I grew up with doctor who, so it's very nice to see one of the earlier doctors being cosplayed. I'm not much for cosplay avatars, but this one is completely original to me. I've never seen it done before! I'm also not one for Doctor Who on the whole these days, and I see too much of the more recent doctors around and annoying me. I find the magic and mystery of the Doctors lie with the earlier incarnations.
Also, although I don't know you very well, I'm sure you don't share the same personality as this doctor, but I have no doubt you'll RP him to a T.
