Drums Icon

This is the beginning of a little project I'm working on for a client.

It's actually for an individual who is starting to do music lessons. They wanted the representation for each instrument they'll be teaching to look like an iOS icon. This is the "drums" icon as described.

Still have Guitar, Bass, Piano, Voice, and Song Writing to do. Let me know what you guys think and give me any criticism.
This is the first time I've dabbled in this style. And this is actual pixels.
