Good:
It does sound cool/tomboyish
Tor is an okay nn
Uncommon but still easy to say/spell
Bad:
At first it looks like a combo of
Tony and Tory, and a person named this might get called those names a lot
Kind of sounds like "horny"
Other:
Looks like an abbreviation or "tornado"
It kind of looks like "thorny"
Doesn't go with
Wren,
Saffron or
Lyra very much. Maybe
Wren.
