Nice layout! Since the resolution is quite small I can't really comment on the details, but I like the overall design of this. The conlag letters look hella cool! The colors are choices are interesting as well - they make me think of something you'd find in a school textbook.

About the font thing: check out Calligraphr if you haven't already. I'm not sure if it is what you are looking for, but this thing is super easy to use and is a fairly simple way of creating custom fonts on your own. I've made a couple of runic alphabets using this, and I've been very happy with the results. It is just the kind of thing that Larb mentioned, where you fill out a template, but I've found that Calligraphr is extremely accurate in copying your letters - especially if you fill the template digitally, when you already have the option to correct and adjust the letters until you have exactly the size and weight you need. Give it a look at least!

Oh, and welcome to the Guild!
