I find the shape of /a at odds with the rest of the font. Every other curve in the font is smooth and elastic, but the belly of /a has a couple bends that look like they won't disappear if the tension is released.
I can say the same about /и. It matches well with /a and looks great, but looks a bit out of place next to /c, /e, /м.
/ф looks a bit boring, the middle of the stem is too uniform in thickness. /l feels more alive.
Overall I like it a lot, looking forward to that /ю
