Can veneers be reshaped after placement?

I have just recieved veneers on my two front teeth! I'm not happy with the result, as they are too ruffled. After the fitting I was asked if I wanted structure in them, to make them look natural. I was told that the glace would even it out the ruffles and give a natural appearance but instead they now look scratched. I really don't want to replace them, as I am content with the overall shape. Can I have the scratch and ruffles filled or even them out, without loosing the nice finish!
