First off, I love what you've done here. Absolutely love this and the whole Circular Gallifreyan writing system too. However, I really dislike the number system in the official guide. Two big reasons, the first and foremost of which being that I can't read it. I very often miss lines or circles inside the many rings or get lost with regard to which ring I was in. I find it extremely visually confusing. The other reason being that it just does not fit the style of the rest of the writing system. This however, very clearly matches the original appearance of the system. Now if I came off as rude, I appologise, but I felt like you needed to hear this. Anyway, thanks for reading, and again, love what you're doing.
