All the textures and opacities should have different names, otherwise, they will work as one, creating conflicts among themselves.
Paint always in the armpit part, to avoid cuts in extreme poses
Save your textures in .jpg , with an 8 / 9 quality
Use the wireframe maps as reference
Check allways with the Minimum coverage guide (MGC)
