Question about molding and casting my statue

Hi everyone, new to the forum and to molding and casting, watched a lot of tutorials on this topic but my first mold has an issue, i think due to it's size or orientation. Been working on a year on a statue and now it's in the molding and casting stage and for a first test i used a small humerus bone that's part of the statue base. The object is 11 cm tall with a wide top of 1.5 cm and the small base where the key is of 4 mm.
The problem is i always get a void in the center part of the piece and only the lower half of the piece gets casted. The mold is a 1 piece mold and made a zigzag cut on both sides for registration and removing the piece, also added a vent at the bottom. I think if there is now way of saving this mold i should use this bone with a femur bone and make a 2 part mold maybe with a cleaner seam line, maybe change the orientation of this bone 180 degrees. What do u think? Ran out of ideas, used a lower viscosity resin too for this and a syringe to slowly add the resin without bubbles but to no avail.
