Hi Anis,

For simplicity's sake, the detail isn't quite exact and I made the model symmetrical, even though the pictures show that it varies in shape from side to side. I set up the three images in the corresponding viewports to trace with curves. For the main section, I used a network surface. I modeled most of the other parts from spheres, editing groups of control points. If you turn on the control points on the jaw and ear parts you can get an idea of how the points are "sculpted". MoI's selection tools and display features make it possible to grab points and move them around. I used the align tool, the scaling and move tools and the new frame editing tool in the MoI v2 beta. If you have any specific questions, just ask... :-)
