I´m usin 1 vray light and 1 direct light

Min r -3 Max r -1
.2,.2 .1 HSsubv 80, Int.samp 20
Second bounce M 0.6
Subdiv 35

HSV exponential Dark 1.0, Bright 1.0
QMC sampler (early term) amount 0.85, noise th .01
Hey! 
40 dpeth for the secondary rays is completly useless.
Set it to 3-4. It will be the same I guess..
Otherwise just increase the HSsubv to ~120
and interpolate samples 25-30 try both see where you get the best time/quality.
Otherwise it looks excellent to me. Also if u plan to use some textures, put on it and that will hide quite some noise…
Looking good, are the rocks displaced? good chance the noise is coming from them if they are.
