Nice work.
Two pence from me though:
In my opinion (and going by what i can make out of the image supplied), for the sake of consistency, it would be worth a try to have that calligraphic, "broken" stroke also on lc u, n, m, etc, in the same vein as it is featured in s and o.
the second thing is that your weights appear smaller with increasing weight (which is a known phenomenon), for my liking you should increase your x-height a bit with each weight compared to the respective lighter one, to compensate for that effect (I assume that all your weights share an identical x-height?).
