Here are both pieces finished. Good balance of light and shadow on the pine needles.
You can see it best on the left half of this sculpture. Look at the deepest part between the pine needles. You can see a clean channel. In the mold that will be smooth and strong.
For molding, what works well, is to have the everything release easily with as little undercut as possible. Silicon rubber is very strong and flexible, but you also need to design for the person who is un-molding the cast part. Too much of an undercut requires a lot of physical effort and wear and tear on the rubber mold.
Same here, look at the bottom channels and see that they are cleanly modeled. The last touch was to gently compress the surface with a flat block of wood. Done and delivered.
Will show more shots after they are molded, cast and installed.
