Nicely done.
Pikachu's facial expression reminds me of a Chinese man for some reason. I like the color scheme and the tone you put on Pikachu's body, plus I got a laugh over him eating that bone. I thought the background could use some more depth or a solid color, but it still meshes together nicely with the drawing. Overall, I like the creative spin you put on a classic character. Keep up the great work!
