Some problems:

a has a larger aperture than c, s, C, S, e, etc.

f, t have unusually sharp overhangs but that's the style you're going for. I am not a fan of IBM's Plex's sharp corners either because it ruins the texture of the font. Either make all corners tight or not. Their argument is "Machine + Humans" or "Tight corners + Soft curves" but your eyes don't give a shit about those things.

a's tail is too long

A, V have a massive opened corners (usually done for small size readability) but Z, X, Y's crotch doesn't. You need consistency here.

Double-story g is hard to justify in a font based on drafting templates and generally doesn't feel like it fits into this type of a typeface. However, its ok to take some liberty here.

Fitting needs work first. S's side bearings need to be cut down by a lot. o, c, e's fitting is much larger than it should be.

There is a lot of work to be done here. I am pretty grumpy generally so don't take this too seriously. Have fun and hope you're enjoying the process!
