Looks like it could do with a little more finishing as some areas still look a little rough. Are you planning to stain the plinth or paint it black? If you are going to stain it I\'d recommend doing a few colour tests too and getting feedback on those.
One thing that may be worth considering is that a lot of folks like to put name plates on the plinth, and this design isn\'t necessarily going to make that as easy as it could be. Perhaps an option to have the front filed down so there is a flat section for a name plate would be worth putting in the plans.
What kind of spinning mechanism are you going to add to it? Some sort of battery operated gizmo beneath it? Perhaps do some research into the best rotation speed for optimum viewing, or is that getting a little too in depth? Nah, it\'s not I don\'t think. They\'d like that kind of attention to detail. Do some tests on people looking at a mini spinning at different speeds and see which one is the overall ideal!
A useful skill to have in this hobby!! I\'ve took Graphics for my tech
