I don’t think this variation on a Mozart portrait is correct because it appears to me like a portrait for a chocolate-box and the nose for example is almost a variation of Mendelssohn-Bartholdy's nose and that is not accurate, because Mozart’s nose was different and made his face look and appear completely different.
To my knowledge there are only two life-portraits of Mozart and these portraits give a completely different idea how he really looked like. With many of the other portrait-variations of Mozart his nose becomes longer and longer and bigger and therefore give Mozart’s face a completely different appearance.
It is my opinion that his real life-portraits also show much more accurately, how his character comes over in his many letters: very deep feeling, very thoughtful, always thinking about his music and more ideas for further compositions and he appears to be very much untouched and innocent about the intrigues, hidden agendas, scheming and ulterior motives of so many other people around him throughout his very short life...
That is why it may be important to study not only the life portraits of Mozart, but also his letters to his father, his mother, his sister and many other people to get a better insight into Mozart’s character, which is very aptly painted in the two life-portraits I have already mentioned.
