In general combat he is a rogue with 2-3 less sneak attack die, less skill points, and a slightly high hp total, 2 bonus feats.
Compare him to the fighter, lower BAB, lower hit die, equal feats, equal saves (adjusted, they are equal), and 2 more skill points.
I dont understand why Listen and Spot would be cross-class but Hide and Move Silently are class? If anything I would see the perception skills more common with a duelist, not the stealth. Gather Information also seems like an odd skill for this class.
As far as ruthless focus I meant that it should grant a floating +1 that you can place in either Attack Rolls or AC for the round. And every level you get another +1. So a first level master duelist would only have +1 to place when entering ruthless focus, and a 5th level master duelist would have +5 to place.
If you dont like that change then keep it as it was, but make it a 3rd level ability, and put Uncanny Dodge at first level.
Just some more suggestions...
