Non Greek user here, but if your fear is of ruining the relationship with Roman, I think you aren’t. No more than any proper italic does, in any case.

I don't have enough expertise in Greek to be helpful here,
but I certainly do appreciate seeing somebody try to break
the short-sighted copying of the Latin UC forms to the Greek.

Wow. Looks like you put a great effort in the Greek. I don't know anything bout it, but, purely aesthatically, I like it. In the 'normal', the serif on top of stems (in /i n p r, etc.) could use a little more overshoot. It doesn't optically align with the shoulder/bowl currently. If you just raise it a couple units, the white space between the bowl and the top of the stem will also increase, which is good for legibility.

Cheers,

Sorry to drift off topic, but be wary of the similarity between your typeface and Minion Pro. I prefer yours as it is, so you don't need to move away from Minion, but just keep it in mind. And what I said about the serifs on top of stems can be seen clearly in Minion. Compare the top of your /n/ and the top of Minion's /n/ and you'll see it.

Good luck!

Thanks Jasper!

Out of the question, it turned into a very Minion-y typeface. And that wasn't even on purpose; I started out with something that looked almost like a Baskerville, started changing things around, and then later realized "oh, now it's Minion!"

You're absolutely right about the overshoots. I'll fix that.

Anyone mind commenting on the Greek caps, though? :-)

- Delta seems a bit too heavy on the right.
- I would also give Kappa a bit more weight along its leg, especially nearing the bottom.
- Eta could be a little bit wider.

I know nothing about Greek though. Other than what I just mentioned I think they look amazing!
