Very minimalistic
They look even more like comic characters now, looking to each other with those gigantic eyes. Those big ears and the lack of noses makes it even clearer that they are comic characters. Normally it would've been a mistake, but in a comic you can draw your own characters, right? They look pretty cute being drawn so minimalistic.
The lighting seems a bit wierd though. The use of colours due to the light is perfect, but the light source seems to come from between them. But I don't see anything. You could place something in the middle to solve that, and it would make the background less boring.
I like their poses. How she puts her hand on her bag (I think it's a bag at least, it might just be a scarf.) seems pretty realistic.
Next to those two kids, you could maybe add something more? Perhaps one of those really cartoony text balloons? With an addition of just a few background details, you could make it look more like a scene, or a picture from a comic. Now I have the feeling it lacks something. Like it's just a sketch, but I don't think you meant it that way.
