Hello, Could you provide larger pictures? A closeup (partial) picture of each, the decoration, foot and foot rim would also be necessary. Best would be if the pictures were taken during the day near a window or with similar lighting. The colors are essential for the evaluation.
As this blog limits picture size, you could upload images to Photobucket, Picasa or a similar site and post the link here. This way it is possible to use high resolution pictures.
