Nice work! 
In the third pic there, it looks like that mold is laid in sideways- is that not the same mold as that watermelon top/pearl belly swimbait in the pic? If so, how did you had pour the belly and get the whole back and whole tail to fill?
Thanks for asking. Pouring and trying to get a belly cut out accurately to shoot was aggravating. I started by using a hot glue gun to partially fill the belly section (not the tail) of the two halves then pushed them together keeping the mold vertical. Clamped, heated mold with a heat gun some to ensure the glue bonded to itself. Trimmed flashing and shaped the blank with a hot knife and heated up putty knife.
Next, I used the blank to cast a mold from pop. After the pop dried I covered the entire cavity and surface with a thin coating of petroleum jelly. Then I filled the cavity with red RTV gasket maker.
I let it set for 2 days over a furnace vent to set up. Trust me when I say you by no means want to try putting the RTV directly into the mold. What a mess!
I also did a back section too.
