Wow, this looks incredibly a lot like a sign I hand lettered for the school that I work in and I was thinking about how it'd look nice as a font. You beat me to it haha

Anyways, the flat descenders and ascenders I really like. I wonder if you might be able to pull out the j and the f and make them a bit longer, same for the p and the q. The almost mechanical look is what gives it its character, play with it some more. Also you might try making the serif a bit smaller on the b or the d (or both). Because they almost connect with the bowl, the serifs look much heavier. It doesn't seem to be a problem for the r, probably because of it's more horizontal approach to the stem.

Cool!

I'd be interested to see an alternate lowercase two-story g...it's the only one that needs a character-width horizontal stroke on the descender/ascender.

Peace,

maybe a two-story 'a' would be a nice alternative also.
have you tried setting some words with it?

The h, k, n, t, u need to be a little wider. check the optical weights of the horizontal vs. vertical strokes (e.g. the descending stem of the g and the left of the bowl are not similar enough. It seems to have great potential. I can see a fantastic display version as well as a functional text version.
