8.) Here we are back to our a Smooth Shaded Preview.  Note the two strange longditudinal, non-spherical, Deformations; at the top of the prop, where they are most noticeable? They were'nt there before we Reversed Normas?  I think whatever is causing these Deformations, is what created the ver straight/dark lines on the surface of the rendered sphere?

I know I'm using a Ball's polygon count, for a Domes', but am inexperienced enough to also know not how far off base that could be?

Lastly, I think the Mirrored Ball is just too dark; but when I tried seeing if the size of the dome mattered, it was hot/cold(a bigger dome burnt highlights fast?)
