The source/basis for the capitals were the 'Roman Style C Capitals' from a speedball lettering textbook and the lowercase was drawn directly in software.

I like the general idea. The colour looks a bit uneven, at least on my screen. Also, the upper serifs on /u look kind of out of place IMO.

altsan - thanks for the feedback. I'm going to come back to this one a bit later and upon reflection, I agree about the 'u'

I find there is a problem with the lower case |u| because it's a reversed |n|. You have to adjust the width of the |u| It should be slightly narrower than the |n|. You will probably has to change the way that the serif is actually drew. Good start overall, but some round letters have a roundness problem, see the |S, s, o,| This problem is on all round letters. Keep going.

fixed the curves (i think!) and am trying to address the colour issue at the moment. file attached
sim - thanks for the 'u' tip!

I have a new pdf to post but can't work out how to do it. any ideas?
