Steve....when we turn a bowl of just about any sort, we look for a pleasing curve that flows. If the curve has a sudden change of direction, or flattens out, then the majority of people will find that shape far less pleasing, so when designing the foot the base of a bowl, try to imagine that the curve is continuous, down one side, underneath and back up the other side. Of course, you need a foot of some sort (unless you're making a rocking bowl), so all that the foot needs to do is to lift the bowl just enough for that curve to flow....so the wider the foot is, the higher it will need to be, but the general rule is to keep it as narrow as possible, and therefore as low as possible - that way it doesn't take the eye so much and interrupt the curve that you've cut.
It's a great first attempt at a winged bowl, and it's made all the better by using an interesting piece of timber that's not too easy to turn. Well done.....Les
