Hey there, Aaron!
Taking a quick look at your World 9 sheet, looks like a great start! One thing to note is that you have Piano 2's loop written entirely on the lower staff; you should definitely bring the right hand part to the top staff. Feel free to ask for help
here if you're having trouble changing clefs or something.
Also, for all of your sheets, take a look
here for help with rhythm groupings - that's something that will make your sheets much neater.
As a side note, please upload your files to a file hosting site (such as Dropbox or Google Drive) and link them here instead of attaching files to your posts. They'll also be easier to keep straight that way. You should also move your Wario's Gold Mine arrangement here to your thread as well so we can archive the submission for now.
