Gallery wrapped canvas - little planet 360° panorama

This is my first “real” Blender project. With some guidance from the forum I’ve gotten this far…whew. This is meant to look like a galley wrapped canvas print of one of my 360° x 180° panoramas as a stereographic projection. I still have not found a texture that really looks as it should. This is the only one I’ve found that doesn’t turn the entire surface to waves? I’m getting closer to what I would like tho-. C&C welcome Thanks everyone Beagle
