Would I be considered a libra?

My Mars, Saturn and Pluto are all libra signs tied for the most on my chart... so is this enough for having libra qualities?

no

The only one that would have an affect on your outward personality would be Mars and that only comes into play conditionally.

I find that my Mars rules me a great deal, but not in the detail of life but in my lifelong big picture ambitions - but it hinders me on the ground, if that makes any sense.

So if this is applicable to all souls then you are possibly influenced a lot by your Mars in Libra.

no. that isn't a lot of libra.

hmm ok thanks.... another qeustion my mars is in libra so if my partners venus is in libra as well does that mean anything

You both will enjoy flirting with each other and there will be a strange pull. But most of ur character depends on ur sun alone. Only some extra details or exceptions are what planets describe.

I also have a libra rising does this change anything??

a bit
