Currently working on a custom lettering for an air fresher company based in Mexico.
After a few pencil sketches I start using ink to have the best contrast between white and black. There is always plenty of work left when I finished the detailed drawing, so after I made a proper scan I use a red marker to point out all things I do and don't like or could be better because of a shaky hand for instance. Trough this way I found it easier to work trough all the points of interest and I hope you may find this interesting.
Any feedback or points added, please let me know.
