I agree with everything Steve's said already. It is good to take comments on board, but you also have to take into consideration where they come from, and follow your own instinct. Everybody starts out with dog bowls, and often there's a fine line between that and a nice bowl. Finding that fine line takes a bit of time.
And yes, definitely sycamore with some nice spalting, and not a bad shape at all. I am not sure about the drooping rim, but overall a nice piece.
