Thanks for the comments / critique,

I'm slowly coming round to using gifs, I'm too much into the quality of the image, but do realise the importance of light weight files on the web.
I could look into a margin.
Yes, I agree the main contact link rollover is not very visible so will be changing that when I can.
Not sure what you mean by the blips. The shadow is intentionally cut off at right angles, maybe its a cross browser thing, I have tested mac - safari and firefox and pc ie6 and firefox.
