too much white for my liking..
i think you could have reduced the white paint/splash into half the size you did.
the cut of the psd is not so soft, try work on that abit more..
the grey images in the white is barely noticable, maybe try add faint shadow or just darken the layer.
i think you should have added a little grunge brushes to the orange imo. well maybe doesnt need but thats my opinion..
