Great looking restoration!  and it didn't take you very long.   What are your plans for it?  Display or operate? I believe your prop profile is backwards but if you will be operating in light to moderate winds <20mph then you should be fine.  The generator brushes don't care which way it spins but the governor does.  In theory, you could disassemble the governor and switch it so it operates counterclockwise but you may have to modify the center pivot plate and bend the airfoil louvers the opposite direction.  It also means grinding out and re-riveting the assembly which is a pain.  
Also, don't make the mistake that many of us have made and not anchor to something before you let it spin in the wind.  
Nice Job!

As Mike was saying, the blade normally should spin clockwise when looking at it from the front, so the copper foil edges would be the leading edge.  What I am not clear on is whether the entire blade is simply mounted backwards which if flipped would then correct the direction of the spin (the holes would need to be re-drilled in the opposite direction to allow the flip).  The copper goes on the thickest edges of the blade, which I think you have done.  Your work looks very good.
