Hi sevilla, and well done for tackling a technically demanding piece of turning. No one could fault your willingness to learn to turn something different and you're achieving a good standard of finish.
If I might pass a little constructive criticism; start thinking more about proportion and the overall shape of composite pieces like this. In this instance, the lid seems to stand too proud of the bowl, which can spoil the flow of the curve, so a solution would have been to have thinned the lid considerably, or even to have inset it into a recess in the top of the bowl. Also, the knob, which is almost a finial, looks a little too heavy.....but these are mall points. The important thing is that you keep at it.....your skills are fine, just develop the aesthetics.
Well done...Les
