i'm using a customized version of lanscape actually, probably the wrong one for what i want because saturation is boosted way up on it, should i be in standard?
Why would you use this setting for a portrait when the setting is called landscape? That's just asking for trouble imo because you are going against what the setting is for....and if this landscape setting is your default setting for all shots, again you are just asking for trouble.

Do pure landscape shots work with this setting?

Bright sun needs a setting, cloudy days another setting, lightbulbs need another setting...etc. One setting will never cut it, ever, because different lights have different colour temperatures and individual settings are set for more specific colour temperature ranges.

Personally I shoot most stuff with the AWB (automatic white balance) Then I correct as needed in photoshop but it's usually reasonably close.
Hope that helps - Marko
