Very nice. I like the two black bands, they sort of frame the main body very well. I do think, though, that the foot is too big. It makes the whole thing look a bit flat footed. I realise that such a tall vessel needs a decent food to stand on, but this is too much, in my view.
I think if you made the two handles from the same wood, with the grain running exactly the same way. and making sure you attach them so that they sit on the quarter-cut sides, then it could work just fine. I would attach them with small metal pins (can be made from nails, and hidden in the joint), but obviously this requires a few millimetres of material in the body of the amphora.
