Drawing Grid for letterforms. Organising what specific characters I will be drawing (Parameters)

Why have i used this grid?
Ive decided to use a (single custom) grid for each letterform because they help define the rules, they bring clarity and order to my typeface which makes it easier for me to keep every letter consistent with a structural harmony throughout the design.
Parameters
Using this grid i have considered the typeface parameters/proportions using the centre square as the basic width of the character in relation to its height. This is a crucial element for me because it will have a massive impact on my typeface final look. Because this is a display font (although i want it to work as a body text typeface as well) i have considered the extreme ligature proportions with the second square. I am going to make this font still balanced with such things as weight of characters to an extent because i want the typeface to remain legible.
The typeface will have different stroke widths throughout but will remain consistent also it will only be one standard weight of this typeface because of time constraints. The ascenders and descenders length is important to create rhythm when using for body text this is why i will be keeping my ascenders and descenders short so the reader doesn’t loose focus.
With this typeface being victorian i have decided to use serifs all with a 1mm median to create a solid a sturdy font although it will curve directly from the median to the height so its not as much slab serif its more of a sharp serif to create elegance and refined letters.
