This was quite good, but I thought the main character's (the grey figure) legs were far too rigid.

A bit more expression and exaggeration in his posture, especially his spine and legs would have made the work appear far more fluid and engaging.

This I thought was really pretty. The ink flows are indeed beautiful and the animations are very smooth and fluid.

I think if you had put some of the animations together you could have created a breathtaking 'landscape' filled with these 'ink creatures' which would have looked pretty amazing.

The scene with the 'flowers' that bloom and spill ink, for example, would have looked magnificent with some of those 'birds' flying above.

All in all though a wonderful animation and well worth watching.
