Help please! Does this look bad?

I ordered this customized necklace. I send them a picture what I wanted which was a pearl necklace with a pendant and three pearl attached to it. Then they send me this. I feel like the pearls attached to the pendant are too small and it looks weird. When I reached out to them, they said it would have been look weird if the pearls attached to the pendant were bigger because it would have been cheap looking and they wouldn't fit. They also said the pearls they used for the pendant are more expensive. They said if I want they could change it to be same size. I dont know. I dont hate it but I'm afraid that it looks weird and it was not what I expected. What should I do?
