Overall, it has a nice, well-balanced feel.
I just have a couple of really nit picky comments which apply to the two narrowest and boldest incarnations. The counters look like they could do with opening up a the tiniest amount. They are right on the verge of disappearing. The most expanded if the three is fine. It’s just the heaviest weights on the first two.
In addition the central section of the Eszett suffers a little too. It is noticeable, though less so, on h, n, m, etc
Other than that, there are two glyphs which stand out fir me; the l/c r (and to a lesser extent the bottom of the l/c v) look a little heavy. Almost like they need a small ink trap, or just narrowing down a bit.
Sorry if that sounds over-critical, but you know what it’s like, it’s all about obsessing the details!
Makes me want to get my backside in gear and continue with mine. Always seems to end up at the back of the queue.
What software do you use, by the way? I jumped the fontlab ship a while back (used to use fontograoher when if first dipped my toes in) onto Glyphs. I much prefer it. Feels more intuitive to me.
As I say, overall, a really nice job. You’ve definitely nailed the even colour thing.
