This is interesting indeed, I would like her to :
-Yea, dye her hair color to black or darker color. She looks gorgeous in it

and grow her hair longer.
-Another Classical Album wouldn't hurt as everyone else said.
-Attempt on Jazz tracks or maybe ambient-lounge-like songs.
-Make more rock songs with that 'in-your-face' choruses.
-Perform her unperformed songs on concerts or mini concerts.
-Instead of promoting album with singular track, she should sing other songs too on TV like singing Slt/LD/DLb too rather than always singing Microphone.
That's my opinion, more or less
