so i'll most probably be leaving my lovely piano teacher end of this year to go get a uni one

so i was thinking of painting her some nice picture (yes i'm thinking like 6 months prior to giving it to her cos if i don't do it in june/july it'll never get done). except i'm not completely sure of what i should paint. something pianoish of course, i was contemplating of doing something like this (i've posted this somewhere here before)

except maybe different colours, and maybe less monochrome, and i'd put music in the background and blah like if some of you can remember i'm obsessed with. i like the image of the girl in it cos it goes with the whole love of being a piano teacher and watching your students progress as they get older.
but if anyone has any other suggestions then that'd be super! like all you piano teachers out there, what would you really love a painting of?
