I think the problem here is most probably the sand, I might be wrong but from the pictures, it appears to have been over-sanded. I think you should have used something lighter. And my guess now is that you just sand it all over again with something relatively lighter and repaint it all over.
Just adding another coat of poly over it will change anything. Just my 2cents anyways.
