Gray North Face backpack with panda keychain

I lost my gray North Face backpack yesterday around 3pm near the Starbucks on Melrose Ave in West Hollywood. It's a 25L daypack, a bit worn, with a blue zipper and a bright orange lining. The zipper has a small green panda keychain and a faded red sticker on the outside. Inside I had my sketchbook, a note from my sister, and my laptop charger. It means a lot to me and I really need it back—some of the items are sentimental.
