Thanks for the positive comments!
Bikebum, I turned the bowl, starting with the outside putting a recess in the bottom which could then be held in a chuck. I sanded the outside(I know I should be able to get a good enough finish without sanding but I'm not at that standard yet!) and applied a few coats of wax. I then turned the inside, sanded and applied a few coats of wax.
I wish I was able to carve that accurately!
