Mr. L!

I think he meant that you could've done a better job in choosing the colours: normally, a good palette is a palette with no colours missing or no wasted colours, which work well togther. In your case, you could do with getting rid of some colours.
For the anatomy: Mr L's arms are in front of his torso: this is very unlikely to happen in real life. His hands seem detached, but that is due to the space wrist-level.
If you change these things on your pic, it'll look good.
