Hi.
If you need to animate the character, then would be better to create your whole model in 3DS Max (or Maya). If you need only a static 3D art work, then use DAZ or Poser for the basic model and refine the details, using Photoshop. I need to note that none of these options is easy. Practice, technical skills, a lot of patience and mostly artistic talent are required. Actually, it is not a task for beginners, because creating of characters is the most difficult in 3D modeling. If you want to attain a similarity with a real person as in your case, then the things are even more complex. The final result depends on your ability to recreate similarity, using suitable software and tools.
I hope these explanations would help you.
Best, Yoana
