If the singer is a non-Bengali, then her pronunciation is acceptable; but if she is a Bengali, then it is not. There is a lack of fluency and use of SOMs in her singing making her renditions as if it is mechanical. This is particularly shown in "Barisho Dhara Majhe Shantir Bari", which is a beautiful song.
