Even though the face repeatedly uses some obvious devices it still lacks unity. I think the error lies not in the forms themselves, but in the counterforms they create. For example the negative space around the k has no relationship to anything else. The g has similar problems. The extension on the M also causes some awkwardness. The 5 and the G also demonstrate the same idea. While it is obvious the device used to create them, the resulting counterforms are completely inconsistent with the rest of the face.
Another note: the tails on the lc letters feel like they are floating. Try decreasing the angle of the slant and lengthening them.
i made this font - a oneline font to get easy the weights from ultra thin to extrabold. for the moment, there are just the illustrator drawings, no kerning - no spacing. i just want to hear some opinions about the forms, and the mood of the alphabet.
