Which set of runes was used for this? Why is C also on K when C is pronounced more like a S sound? Why is there no rune for K? Are there more runes that got left out?
Not OP but:
C is an S sound before soft vowels (e, i, y) but a K sound before hard vowels and consonants.
Think century vs. cancer.
Trying to map a phonetic alphabet on to an alphabet where letters can have multiple sounds depending on the surrounding letters always requires compromises.
That said I'd say that the following letters have the wrong rune (as elder Futhark seems to be used for most runes):
F: the rune used is from younger Futhark instead of elder Futhark
Q: is pronounced as a K but has the rune for a "ng" sound instead.
U: looks more like younger Futhark than elder, probably for aesthetic reasons
V: has been given the rune for younger Futhark U. Should have the same rune as W
