you mainly make some changes in notes which makes the music a lot better most of the time but in this case they were quite a few things not likable , for me at least . first of all the timing was not routine as it should be . I mean it went well but came out to be horrible after a few seconds , the worst part of it was in second 30 of the music , it was devastated indeed if you've heard it . second , the unity of notes placement . they were quite compacted in some parts but some times sheet was barely naked of notes . third and the last problem was not keeping Originality of a well-known music . Dealing with such a famous and remarkable music , a little deflection of the musics way of expressing will cause a definite failure in public sight . it's up to you any way and sorry if I bothered you , writing a long comment .
