So, now that I know the final pose, I need to repair everything that becomes broken during the previous stage. Now it's easier because the new Zbrush version (4R8) includes a new gizmo that makes the moving and posing steps much easier than in previous versions.
I sculpted a new face instead the mannequin one to fit better the character's one. and also I started to add small elements like ribbons.
We need to add the insignia too and also a texture to the dress.
