Another short, unscripted but we hope you still enjoy http://m.youtube.com/watch?v=tYVTSAeMAd4
A cooking show: Super Chef
I watched the first couple of minutes. My critique would be that you're better off scripting so that you have some jokes in within the first 30 seconds and then regularly throughout rather than just a take on a certain type of TV presenter. I couldn't hear the lyrics that well in the song, but if you're going to start with a song make sure it's funny throughout (don't ride on the fact it's a song and people will listen, each line needs to be either punch or set-up).
This was double posted in Showcase. But it is interesting enough to bump in Critique. As I said previously, confident and charismatic performances, and for unscripted dialogue there are some choice turns of phrase, but eight minutes of the same joke is asking a lot of the viewer.
I agree, very good screen presence, but needs some gags - you clearly have the lexical desterity, so hone it, is my advice.
Also, it might not really matter, but I felt it feel between two stools of satirising chummy armchair food presenters and pretentious, flowery food critics, fo the Jilly Goolden variety: perhaps you might get a good rapport going by writing a sketch with one of each?
