UC & lc wide - wght: 100 | wdth: 151 | slnt: 0 | GRAD: 0 | opsz: 14

lc

* f+i clash - Make the top of f less wide.
* a - lower left of a is a bit too heavy.
* joins in g especially the upper one don't match q and are darker. The bowl of g is also a bit wider and bit more eye-catching than seems to be useful for 14pt opsz.
* z - gentle compensation at joins would be nice here. 1 unit less weight too.
* n,u - the subtle contrast in this is great but it is getting slightly too strong in the upper right of n. Not in h though. It is also too strong in u.
* asterisk is a bit asymetrical ( not a letter but I saw it )
* i - this dot seems a bit too small to me.
* y - the terminal needs slightly more weight

UC

* C - upper right is a bit too heavy - the whole thing is very slightly but the upper right is even more.
* K & R - diagonals slightly too heavy
* S - Middle a bit too heavy
* G sidebearings are too narrow - compare with OO or CC
* A & V - these feel a bit too light
* I - a bit heavier, please
