Non-symmetrical Character walk left animation.

I am new to using Unity and I am more of an artist than a programmer or developer. My question is, does anyone know how to make a non-symmetrical character look like it has not been mirrored when the character moves to the left of the screen? Based on what I have seen it may involve changing the script that mirror's the sprites to actually switch them. Or is there another way by using the state machine to have two different walk animations one for moving to the right and one for moving to the left?
