if your legs already look smooth, i'd stop the cardio 1 week out.
flexing is going to be key and being 1.5 wks out adding in too much at this point can be detrimental as well.
be sure to get some good color on, as that will help bring out contrast in your legs to define the separation a little better.
stage lighting can also help here, and don't over oil or let anyone other than yourself or a buddy put on oil (most use PAM aka non stick spray)
some ppl seem eager to help, then load on the spray and it kills everything.
