LOVED my temporary crowns.. Really upset with the final results. I feel like I have a HUGE overbite now. Can they be adjusted?

I can see what you're referring to. Your temps were actually a copy of your teeth prior to starting. That's why they were comfortable for you. Ideally your final crowns  could have been similar. Your teeth were more vertical than the final crowns. Unfortunately, there isn't much that can be done to your present crowns. The only real way to address it is to remake them. I would speak to your dentist, I'm sure he/she wants you to be happy. 

First, congratulations on your new smile. It is a lot of work and I think they are a nice improvement!
I would encourage you to wait a little before making any big changes. Your temps look like copies of your original teeth but whiter so they felt very "normal" to you. I agree that your final crowns/veneers have more curves but I think they look more feminine and more natural that way. If you look at the edges, they are actually really close to the same position. The face of the tooth simply has  more contour and the edge is slightly longer and more rounded. Your canine was in crossbite before and now is built out with the veneer. That will take some getting used to. It could only have been avoided by doing a quick course of braces or invisalign to move the teeth into better position before the prosthetics were done. Without the orthodontics, this is a nice camouflage. 
Let your dentist know that you may want to come in to reshape the edges but that you will take some time to evaluate first. I have had many patients over the years that want to make changes because everything is so new but I have given them the same advice I have just given you. When I see them at their next recall, most have thanked me because after living with their new smile for just a couple of weeks, they decided that everything was great.
If you decide that you want the edges reshaped and polished, it is not difficult at all. Just remember, we can always take away but once we have taken it away, it can't be added back!
