this is tight. especially at pixel. least convincing...hum. i think neat trick of font sets is that although there may be a glyph that somehow could be more, the consistent appearance of that glyph somehow makes it work. no? that said, i would consider narrowing the width of the f. many times i just crop the arms and although it varies the spacing from other characters, it conforms a little better. just a suggestion. but nice once again :)

hey, never mind about the f - it's just fine. i re-read your sample and "off" is killer :)
