I think they work pretty well.
I can think of a few tweaks here and there, but the biggest thing is the bottom serif of the “7”: too jarring. Solution? I can’t seem to think of one…  :-/

Try this:
The foot serif of the “7” might be fixed by narrowing it slightly and smoothing the bracketing. Use the “4” as a guide, as much as feasible, only make it slightly wider.

Good luck! The numeral set looks like a nice solution overall.

the 7 is absolutely the weakest part of the numerals. I’ll play with it some more and see what I can come up with. Thanks.
