Cheers again guys, theres some good advice in there which makes sense.

In the job securing portfolio I was given the link to, there was walk, talk and run cycle animation, some examples of compositing, match moving, and some product viz animations of a camera and a phone. So I have gone for making my phone. Im about a third of the way through modelling. The aim is to get a good, solid, technical model, and then give some nice reflective lighting and material makeover. My phone is a sony cyber shot phone, with a screen that slides up and a sliding camera shutter on the back. If I have time and if I am able I might try and animate a pan around camera with the moving bits of the phone sliding open. Hopefully I can then send that and the animated matte painting camera move I did back in spring...
