The signature should be repeated in the changed clef. After a change of clef in the middle of a score this is, of course, not necessary.

(1) Placing the sharps or flats at the wrong octave. The first sharp should, in the treble clef, be on the top line, not in the bottom space. And the second flat should be in the top space, not on the bottom line. The customary way of writing signatures is not, in the writer's opinion, invariably the best.
