A little basic
Okay, so the background has a fade, indicating the presence of a light source. Good, but a problem occurs when you fade too far either way, so you start with white and finish with black. Since you've not started with white, consider trimming the black a little and you'll end up with a better looking background. Also, consider curving it slightly away from the light source.
Moving to the foreground, you've messed up the shading entirely, since the light source is shining the wrong way to cast shadows on the left of shot, yet the face is in shade. The drawing isn't fantastic and you need to zoom in and use a smaller tool, to give you a better degree of control over what you're putting into the picture. More control gives much more detail.
Next time, you can think about putting other things in the picture, such as background furniture, rather than leaving a blank space, it looks untidy in works such as this.
