Thanks dave. Some things cleared up on my mind. + I read a few more things on different sites. I am actually thinking of using the zbrush retopology tool to make another low poly model. I tried to keep the subd level low in zbrush to see if i could get the best result. The reason i did this was to use the zbrush retop tool. Alternative to that, i was thinking of using the NEX plug-in in maya. Thats why i kept the subd low. But now it seems impossible to use nex.

I cant lower the subd level on body mesh anymore. I am trying to find the best polishing ways to fix this issue. Remesh, dynamesh, clay polish seems all the same to me. I think i need more time on this one : /
