Well after asking a few people, I decided to actually try and design a font (which I have attempted to do in Illustrator for the moment). The idea was originally based on sigils though this has now evolved into also being inspired by Art Nouveau. I know there are alot of issues with it (especially the K), I also have only done a few of the characters atm. Any advice would be appreciated.
Regarding that k, the leg of the k feels a bit weak, needs a bit more weight, particularly at the beginning. Good job having it come off the arm instead of from the vertical stem, keep that join the same and thicken it to the right.
In terms of the actual shapes, I think you need more coherence in the reasoning behind the different modular elements. You have very playful, sharp and bendy arcs and the bowls, but the roofs and bottom of the serifs are blunt straight lines. A similar contrast of shape vibrance happens between the mathematically straight stems and round shapes in general. And by this I am not siding with either, nor am I saying the contrast is bad per se, only that it appears undecided. It is good to start with common shapes and "generate" new characters from those blueprints just like you did. However, especially with mirroring elements you need to be careful, as it can have a very unnatural feel (for example the j tail and mirrored p bowl on the q) - unless that is part of a victorian machine-made cast iron charm?
Keep drawing, keep posting, it is an interesting start!
Also pay attention to color — your /o is much lighter than your /p, for example.
The /r strikes me as wide, and the vertical stump cut on the left top side of /t feels a bit out of character.
Glyphs Mini might be a good choice for you, or Glyphs, or Robofonts, or the (free!) beta of FontLab VI.
