Sketch with emotion

This is a sketch I made after Don Bluth critiqued the first drawing I asked for help on. Two things he emphasized on were to try and avoid twinning, which will make the drawing a bit stagnant and the other was what makes the character unique with how he thinks and feels. I tried my best to show a core feeling of what makes this character who he is and the thing he experiencing right now in his life is being rejected by others and feeling absolutely alone. Enjoy the sketch and I hope I was able to get this feeling across.
