thats probably one of the easiest to start with. Just make sure you cut the tuck grooves deep enough so if you have any extra skin you can tuck it easier. Cut the grooves under the arm pits and the inside of the legs. How did you skin the animal,? that matters too. If you cased it back to front it shouldnt be to hard to deal with. And use a lot of clay to fill in the muscle. Let me know how its going.
