Myna's predecessor was a customised version of Source Code Pro. but i've changed a lot of glyphs by borrowing designs and modifying glyphs. so, it may not look like it at all now.
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.
