What would you recommend for my ugly front teeth? (photos)

I would agree with this approach. Making teeth smaller than natural would require some sort of movement (invisalign) to close the extra spaces where there used to be tooth structure. 

if this is the way you bite, this means that you have an overject, and the way your teeth match is not the proper one, also the shape of your teeth , do not help, so my recommendation its to work with veneers ,and that way you can change the angle so they would look more even , and more nicer.6 veneers would make a big change.
