It's not round, no where near.
A few of the Disciples commented on this on the "Novelsforbegginers.com forum"
A rookie mistake on day 1 to be honest, when he was making it God did not have enough water on the clay, basically he rushed it. IIRC, he stuck a pencil through it and noted that it span ...kinda OK but was not really how he imagined it. Bit of a face-palm moment really, this too went wrong. Clay on big beard, getting in a bit of a mess. Anyway quickly sorted, grabbed a towel, wiped face (Remembered to put towel in Jesus's rucksack for up and coming visit to relatives. Got my face on it, what can go wrong. With the right biological powder that will come out).
In his defence, he was doing it in the dark. A bit of forward planning would have done the trick, Microsoft project or similar. Light first, then pottery but it was a really busy week.
