buenos. here's my two cents:
-the uc & lc "c" seem top heavy. same problem is there with the lc "e" as well. if you were to extend the bottom line this could be avoided.
-one thing i don't understand is why does the stem in lc "u" and "y" slope, and it doesn't exist on any other stems. i suggest that you put a slant on the top of the leg on the lc "k" and add a slant to the end of the hairline in the lc "x."
-the uc "W" just doesn't do it for me, same thing with the lc "w." the lc "w" looks like it's 2 v's put together. try to integrate them more. the uc "W" looks funny with the extended line in the middle.
-the stroke of the uc "M" and "N" seems too thick compared to the rest of your uc.
I love your letter forms. They're all very light and airy. It's going to look great with just a little bit of tweaking. I hope that my terminology was correct
