This reminds me a bit of Lexicon with the mini flourishes. I think the bottom of 'S' needs work. The curve looks too flat to my eyes.

Thanks for the input, it's actually the s/S which I'm having the most problems with.

Interesting, challenging project. The curved terminals have charm but are a tough fit as you acknowledge. Maybe if the strokes weren't so insistently monoline (introducing a slight consistent contrast, or thinning bowl strokes as they intersect more dramatically), the thinning flourishes would be a better fit.

Are the flourishes on the figures much more pronounced on purpose? That 9 seems unbalanced, and also may be violating the open apertures you talked about on your website.

I'd make the ear of the g more old-fashioned, curved and "flourished."
