Your code is counting smilies when it shouldn't, read the error message:

The Array [~:D, 8P, o8p, o~DD, :p), 4), ;2X, ;~X, ;x, o;P, 4), ;pP, :x, 8~X, 4pX, 4X, ;D, ;P, :oP, ;D, -8-D, odx), o), ;p, p~), ;8), 'dP, (x, ;D, o-), 4-d, odD, oD, :~d, o)X, :~P, :pp, 28), :~x)] has expected:<3> but was:<4>

~:D isn't a valid smilie. Not a kata issue.
