I think if you have an eclectic style it could be fabulous:

Wish you had said what kind of tin ceiling, its color, etc., your style of furniture, existing flooring, and would help to know year house was built. More details! Not having additional info, my first thot was to put the crystal chandelier in a more unusual location - like a bathroom, or porch even. My second thot was that if your initial gut feeling was that the chandelier wasn't quite right in the dining space, then I would trust your gut.
