So this is a self portrait? Again I point you to Karsh's self portrait. Turn up the fill, pull the accent lights forward so that they're at about 45 off his nose and turn them down. You might even want to put snoots on them. It looks to me like that's what Karsh did, although he may have had a main light to give it the Rembrandt effect. Note that there is almost no butterfly shadow under the nose.
