it looks really bad imo.
1- the psd itself looks bad quality. try use some sharp filters on it, then blur it at the end (not much)
2- add some golden gradient to it and reduce the white on he psd as its not clear at all.
3- one thing you can do first, you need to increase the size of the psd. Then do the things i mentioned on the previous points.
post the modified one, lets see if it got better result from it?
