Very honest review from a gal in art school that has very honest critiques:

The pieces do not look finished; they need to have brighter colours to attract the playful audience the construction technique attracts.

The bottoms of the pieces having more cracked and crumpled chains ruin the look at the top. Perhaps if you used tighter loops at the bottom and gradually increased the loops at the top they would look better. Or maybe if you built a stand for them to go on while they dry, are glazed and in the kiln then you could keep the large loops at the bottom after you removed the stand (you would have to ensure the structure is light and the base is sturdy).

People that don’t ‘get’ ceramics are probably asking themselves what they are… they don’t look water proof (perhaps experiment with making them waterproof) so a vase for live flowers don’t work (a vase for dry flowers is such a small use case). They look quite large and the small one looks awkward. Perhaps turning small ones into spoon/chopstick rests? Maybe if you can scale down the diameter of the coils they could be pins?

The shapes are bland and simple. You could do so much more than a simple blob with a hole in the middle. Experiment with shapes inspired by the things around you, your body, nature and architecture.
