The expressions are getting better, keep it up. I also like the expression on the man. And his mustache adds character to his expression.
Some advice however. Whenever your going to draw a box be sure to make it 3-dimensional, so that it looks like a box. That would be hard to do in this picture, since the angle would allow it. But the box needs to appear to be thick and have dimension. Otherwise it looks flat, and so does she.
Good work though.
