Debating on Getting 10 Composite Veneers

I have many insecurities regarding my teeth and smile, and am seriously considering getting veneers in order to cosmetically fix the problem.

As you can tell by the photos, my teeth are straight but are so high in my mouth that when I smile you can only see the bottoms of my teeth, leaving a huge space in between my upper set of teeth and lower. Would getting veneers be a viable option to lengthen my teeth? If so, would there be a limit to how much longer the veneers can make my teeth?

I'm also not sure if people ever get that many composite veneers? I've heard about people getting that many porcelain ones, but never that many composite. Is that something that I'm able to do or something that would satisfy what I want done? The reason why I'd choose composite over porcelain is that I'm only 17, and my smile can still shift a bit, so I'd prefer to do the less invasive procedure in case something changes. I'd probably get porcelain ones in the future if this goes well.

Clearly I'm a bit clueless on the subject, so any help would be appreciated. Thanks!
