Cheers for the comments so far.
SwerytD - Suppose the material needs work then? Damn, I quite liked it (then again, I suppose I would).
Will Cam - The music's down low because I wasn't that sure of it. Listening to it this morning, to my ears, it sounds acceptable (though I'm preparing myself for someone to tell me otherwise). I might redo the VO at the end. Unfortunately I've shouted that line into my microphone so many times the neighbours are probably worrying.
Ben - Was thinking of adding a background. My reasoning behind the lack of one was that it upped the boringness (oh, turns out that really is a word) in what's meant to be a "crazy adventure". Might add an utterly random or mundane BG to it. A photograph of a thimble or something (would that work?). I'm sure I've used something like Merv 2's voice before. Would get other people in to do some voices but for something so short it's a bit of a bother.
Again, thanks for the comments so far.
