Thanks for commenting again =) It's also nice to have comments with critics, it makes you grow ;p
Yea just so that you know I am a graduate major in piano =) so yea I know that part can be a pain in the *** but I can do that and yea maybe glissandi would be a better idea. What I should write in the score at that part is *play with tempo*, or something like that 'cause I don't want it to be a strict classical piece, but something you can play with, but obviously still fast.
8va is an option, but it looks cool with ledger lines too =p
hahaha thank you for listening!
