I have been looking quite a bit at blackletter writing[1. Things aren’t perfectly angular yet in this period, i.e. the first quarter of the 13th century.] recently and I just randomly doodled around using Ayeri’s script, Tahano Hikamu, as a basis, today:
The letter 〈ba〉 is slightly difficult because it’s looking left whereas most of the other consonant characters are looking right. The difference between the placeholder consonant and 〈ra〉 is also very minimal, but that it is in the regular form (first rows) as well, plus similarity with 〈ta〉. I’m not perfectly happy with that 〈ha〉 either.
