Haha I like their individuality.
Noble-raised thief and passionate artist.
Their base stats and class growths are good, but I think you forgot the "min of 15 points" in a stat when doing personal growth.
So, Kalyna's HP and Def, as well as Mahina's Skill, need to be changed.
Also, it's "Vulnerary".
But yeah, besides the above things, it looks good!
First of all, I love how you got three classes with a "something +2" as their starting skill.
Ok one blurb question: If Tamma was orphaned at a young age, how could she follow in her family's traditions? Would she know these traditions or are they the traditions of her new family?
It would almost make more sense to just not make her an orphan.
Can you put [Flying/Beast] after Pegasus Knight (for Class) and [Beast] after Troubadour?
Oh and [Effective against Flying] for your bow.
For your Heal staff, the small amount is 10 HP ( and I've decided + Mag/2 ) [ So your Heal is 11 HP ]
Stat-wise, there were little problems, but...
Archer Def class growth is 10, not 15. And your Archer also has another 5 points left to spend in personal growths.
Besides that, it all looks good.
