Nice! What led you to choose phases of the moon as a design motif?
There was one barely visible on the original photo if you look very closely.
Edit:
The Moon together with the Sun (and to a lesser degree also the Stars) are also important for dwarvish culture, but as the Sun is an explicit "manish" celestrial body, and dwarves invented e.g. moon letters and the Moon figures explicitly in their songs (next to Stars and the Sun, but those celestrial bodies already have their "children") etc. it feels fitting to stress the dwarvish affinity towards the Moon more.
The Moon has power over werewolves and - even if less pronouced - over vampires too (note that the phases on the spear do
not include the full moon - which is associated with greatest power in those evil beings. They are the
other four: waning crescent, waning gibbous,
waxing crescent and waxing gibbous.

The Moon also symbolises the cycles of (mortal) womanhood ( - I personally do not think that ellith have cycles, given thet Arven is still able to bear children in her 2700s, it seems it fertility is more an issue of will and mastery of their spirits over their bodies than a power that is bound to seasons and fixed times that comes upon them and leaves them regardless of their will - like it is with mortal women).
So if the spear is of dwarvish origin the Moon seems a fitting symbol, as is the fact that it will be a device used later by a mortal woman against a vampire.
Maybe it was made by a dwarvish lady?
As such the fact that it is there on the original seemed very fitting to me - it "made sense". ;-)
