lovely face details and colours...
athough i dont like how you have added lighting on the eyes and above the hair... it destroys the linework... also i found it quiet hard to work out where the notes connected... at first i though her hand was the blue note beacuse the sleeves join up to it... i think if you put the lighting under the line art and gave it a background... or even a simple one it would really bring it to life... at the moment the white is really killing this picture... a darker or even deep red background would give it a better all over feel... but thats just my thoughts...
