Nice. The weathering looks great, as does the hat. Looking forward to seeing a lot of these customs once the new movie, and a new sculpt based on Haley, comes out.
Initially a part IV but wanted to make him look like a part II jason.
What i did first is resculpted with miliput the upper part of the body and tried to gave him that bull neck look he has.
Then repainted the neck, face and arm to match.
I know the face sin't quiet a part III but still close enough for me.
I removed the cut in the mask by filling it with putty then repainted it to match the part III mask.
