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.
