You're quite welcome. I'm curious what tools you used to get the curves to match the perspective. ^_^
Basically it is a five point perspective. I have sketched the four point perspective wireframe sphere on paper then measured it and transferred it on the canvas. It had to be fine tuned because it wasn't pefect even I think I measured it correctly. However I had to satisfy my eye 
The rest was done on the canvas. The intrusions and extrusions of the surface are basically a one point perspective.
