I think it would benefit from a light pruning, but do it in the fall. How much to prune? So that I can stand underneath without getting bumped or poked on the head. I'm 6'1" so everything must be pruned at least that high. I want to walk completely around the trunk without leaves brushing me or anything poking my head. This would make the tree more inviting and aesthetically attractive.

Thanks Bathgate that's good to know I will wait until Autumn as I would have done it now.

Good idea to wait until autumn. Maples are known bleeders (We love our maple syrup). They won't bleed so much and less pathogens to take advantage when the temps cool down. You can even wait until February.
