I'm struggling with the proportions of this piece....as a practice piece to get techniques honed, then it's fine, but the base looks too heavy whilst the goblet-bowl looks heavy, yet far too small. It reminds me more of a shallow Martini bowl than a goblet. Multi-axis work really isn't my thing, which is just a personal take on it, but the work on the stem looks to be well done. Sorry that I couldn't be more positive.
