#1: I think the keys should be right side up not upside down. Also, the grand piano "B" should be more noticeable as a grand piano. I kind of like the idea of being able to see the keys in the grand piano "B", though they would be small at that scale.
I really like the revision!! Is there any way that I could see it with a few different font options (for the "att" and "eilis" that is). I picture something that looks a little bit more edgy and hip. This has to be something that a teen girl or boy will want to wear on a tshirt. Thanks so much!!
