File doesn't seem to have attached, Rob.

Whoops, Preview showed it but then it seems to have disappeared. Back now. Thanks.

Handsome typeface overall.
Some random thoughts:

A very good overall design, but I don't like the combination between some very traditional, rounded terminals (/a/f/r/s/) with the unusual, contemporary cut of other elements (for example, upper right serif of /k/v/w/x/y). As you used a sharp cut in other parts (/b/d/u/) and uneven serifs (/m/n/) it may be more harmonic to use not-so-rounded terminals.

Diacritics (acute/grave/circumflex) are misplaced. You can take a look on Slimbach's serif fonts to verify an optimal placement of these diacritics. Observe that this taller style of acute/grave will demand a different shape in uppercases.

I like your /k/p/m/n/h/K/R, but /g/ seems distorted and /e/ is falling to the right.

Comma seems identical to Greta's.

Thanks, guys.

@riccard0: Working on them. Seems right on all points.
@Freiberger: I understand why the terminals could bother you. I'm going for a transition-kind of letter, a seventies' Baskerville perhaps, which suits itself to rounded terminals. In the /C/G/S/ I do use different terminals. Maybe that's a starting point. Not sure about the diacritics yet (angle especially), but willing to see specific examples if you can find them. /g/ has been under constant revision ever since the start, which might be a sign. /e/ gets two counts here, which says a lot. Thanks.

Re: Greta: hadn't seen that at all. That might very well be the only thing it has in common then. Thanks again. Keep 'em coming. I know I will.

I'm myself developing a serif family and /g/ is by far the most difficult character to me. It took me dozens of revisions until I got a decent design.

The comma got my attention because I like very much the shape you used.

About diacritics, the main problem is not with angle but with position. Acute and grave are not centered or aligned to character limits. They must be slight dislocated from the center to te direction the accent points to. You can use a rule like this: acute have one third of its length to the left of middle and two thirds to the right. The opposite with grave.

Of course this is a very general rule. You can adopt different positions and, except for extremes, it would not be incorrect. But some positions works better than others. Take Minion, Times and Meta Serif: each one has a different criteria, but I think Minion works much better (as I'm a native Portuguese speaking, I use acute, grave, tilde, circumflex, cedilla and dieresis regularly).

You may also consider acute and grave to be shorter if you plan an extensive language support. Letters with two diacritics above will need very much room over uppercase limit.

Ah, yes. Yes, positions are terrible. You're right. They're not high-priority at the moment as I'm mainly trying to get the shapes and metrics right. Thanks for the pointers.

Re: language support. That's the part that's vexing me. I want to use this face for my own print things (10pt text and the works), but supporting many different languages is more than logical as a selling point. I don't know where I got the idea for the highly slanted acute (well, it's in my handwriting), but I was happy to discover it in Trinité and Lexicon. Dutch typefaces. Go figure.

Here are some updates. A pointy, pointed-pen-inspired terminal that has some of the sharpness other shapes have as well (/&/g/k/) and some more.

An example:

The update shows a visible improvement on /g/ and /e/, but /e/ still seems a bit inclinate to the right. I prefer your new /s/. /f/ and /y/ are very good.

Thanks again, Igor. I've updated some glyphs, tweaked some things. Highlighted are some characteristics that are new since the first PDF or are actually leading the rest of the set. I will update here with the italic soon.

And vanilla, easier on the eye.

It's a very nice design. What I noticed is that there is very little spacing between words, in the "What is entropy?" and "Abstract objects and mathematics" sample texts. Maybe that is due to the fact that the typeface hasn't been kerned? The single words doens't look "isolated" enough in the line of text. I guess you should work on that issue - the relationship of space between glyphs pairs and between words. Besides that, it looks like a nice typeface.

I've uploaded a new sample file to the original post.

Updates include, but are not limited to
· All-new metrics
· Redrawn ligatures
· Some troublesome glyphs cleaned up

Let me know what you think.
