It's a bit too blended on the edges, don't erase so much next time. The colour seems a bit wierd too, maybe adding a photo filter/gradient map could bring some of the gold out!
You should add some text just to finish it, but the smudging looks very cool, and (if those are clipping masks) they look great too. It looks nice on the white BG but maybe add a c4d in the back just to add a bit of depth. :P
Overall pretty nice just don't erase so much of the render.
