Maya 3D environment

I have been working as a VFX technical lead in LittleYellowBeetle media Since 1 and 1/2 years.This is a 100% cg environment except the sky and a little of the BG. I have done this 3D environment in Autodesk Maya,Foundry Mari & Sped tree as a part of my show reel.

I have created it fully dynamic i:e: the trees are responding to wind,Smoke is coming out from the chimney, have some camera animation etc. But i have tried thousand times with hundreds of different ways to accomplice the batch render process. Have optimized it as much as possible but perhaps it could be possible. Friends please suggest me some ways to do the batch render.
