I think the Bowl, in bowl effect of the first 2 images is very clever. My first thought was it was two bowls made to fit together. Well done on them.
The shape of the Damson Vase is excellent, the long sweeping curve really hold well on the colour of the wood.
The small red oak bowl, has equally pleasing curves, I like the way it has no foot and has to find its own balance point to sit on. If it is still green, I think you can expect it to develop a crack or two, its a lovely wood, but very prone to cracking, hopefully they will just enhance the work and not detract from it.
