Some of these seem subtly off. For example, on the orange "number field" clock (https://clocks.dev/clock/number-field), you can't distinguish between 12:10 and 10:12. On the "word field" one (https://clocks.dev/clock/word-field), there are "X"es in lieu of unused characters, which makes the emergence of words a lot less mystifying than in the original "word clock" design this is based on. The "temporal exposure" one (https://clocks.dev/clock/temporal-exposure) has weird off-center bands in the blurred area. The "figure hands" one has text sticking out of the drawing area, etc.

In the "number field" clock, the hours are always along the top row only. 12:10 and 10:12 look different.

I think the one you are calling "figure hands"... if you mean the one where hands are numbers could just use better styling overall. Two colors, different sizes, better choice of font.
