Looks good.  Somethings I do, if you dont mind me mentioning, is to use 3% peroxide and simmer it.  I wrape the antlers, real tight with innertubes to protect them from the peroxide.  That way you do not have to touch up the antlers when you are finished.  I have also burshed on 30% peroxide to better controle it so it does not disolve the bones too much.  When Im finished, I like to seal it with kilz oil primer.
