My own font took on the blockyness of the IBM 3270 terminals. Now it has a ton of glyphs those terminals never had, but I tried to remain faithful to its original design principles.
i've not been faithful to the original design of Source Code Pro or even Fira Mono or Ubuntu Mono (from which i also derived a lot) but do try to stick to a simple geometrical ideal with only a few exceptions.
Not everyone likes it, but I do.
