Failed attempt at molding the sea #2

Now I save the master and tried a plaster mold. did it succeed? nope, I never managed to wipe out the plaster mold without destroying the '"sea'" this morning.
14€ of resin thrown out of the window, the original master for the sea destroyed in the process, I am *not* happy.
Will have to find another way of making the mold. I am currently thinking about wax ..let's see in a few days..
I have to do another master for the sea bloody hell.
