1. You should cut these down a bit, especially to get rid of the 90 degree angle at the front.
Anovos is famous for the return edge on the neck splitting/cracking (red arrows). If you want to keep that return edge, be sure to add a thin (1/4 inch) shim** behind it. I would suggest losing it altogether.
** One solid curved piece... don't use short ones.
You can trim the tops down as much as needed, just follow the existing curves. BUT, do this before final fitting (gluing the backs together). VERY important!
The bottoms of the thighs can be kept like they are, just sand down those rough edges. Keep up the great work, and keep those questions (and photos) coming!
