There's a lot about this that I like. The 'saggy' shape looks relaxed and comfortable, and is echoed by the shape of the lower half of the finial. I also like the way that the finial/lid sits on the top of the hollow form; it really works well. What tops it all, for me, is the colour and the apparent texture, it really brings the shape to life. However, there is one element that doesn't work for me, and that's the upper half of the finial. I feel that it's too straight over its top half, and could therefore have doen with being a bit shorter, or thinner, to keep the curve flowing.
All in all, a really good first attempt at colouring.
