Perhaps make the bottom loop on the treble clef more like an O and overlay it with the same font as the rest of your name ...
In the second one you could just put the O in the piano, in the third one you could make the treble clef a different color - like the small blue clef imbedded in the larger one - and, again, have the lower loop the same color (in this case, black)as the rest of your name ...
I like the basic premise, though ...
