What's that I see up there? 16/16 coins used?
people are gonna get confused because we can only use 15 coins which you did do properly by adding the triangle to reduce it to 15 coins used but out of 16 makes it look like there were 16 to start with. not to mention that you put 16/16 which is both not allowed and not mathematically accurate to your totals.
The vibraphone was my favorite part because I adore mallets.
