Hola soy consiente que no entiende mi idioma pido disculpas por eso, bueno esto es lo que tengo hasta ahora usted que opina. http://youtu.be/jAgw0rdzFsU
I have looked at your torso... It definitly looks too big in all dimensions.
Sicing it down, would result in a loss of detail and I feel that there would be too much to slice out.
If it was my piece, I would resize and repep.
