I like what i see! Many characters seem to have more personnality with those colors.
One thing though, maybe it's just me but, the lightest color is always too dark. FE8 have high contrast between shades and the lightest one is usually (not always) ''overly'' bright.
that apply for hairs, but also for armors to give them a shinier effect. Merlinus' scarf, Fiona's hair and Hector's armor are the palette reminding me the most FE8 style.
Than again, take it or leave it, just my little 2 cents
