Veneers: top and bottom don't match, left and right different shapes and sizes, I can see my tongue through front teeth! (Photo)

I have just had my teeth veneers (front 8 each arch). The dentist did my bottoms first, then the top a week later. Both are meant to be B1, although the top are yellow because the teeth were dark underneath. Also, the dentist trimmed the top right veneers down far too much and the bottom right not enough, so there is asymmetry. Finally, the biting edges the the top two front incidors are very thin and sharp. My tongue is visible through them. What are my options?
