Hi there! :] Overall i think the image captured what you were going for-- an emotional response to the situation. The sadness on the focus character is very apparent. The image looks good, especially the background which is something that a lot of artists struggle with, so good job!

Three major tenets of character acting are the face, teh hands, and the feet. Because the faces on most of the characters are obstructed, we're left to retrieve the acting from visual cues in what you've left us with: the hands. The character inside the room in the yellow jumper has her hands balled into fists. She looks like she's going to punch that dude in the throat with all that tension. To alleviate this, I'd suggest giving her hands a more relaxed position. Maybe touching his elbow or, at the very least, laying open on her knees instead.

On your main character, I'd like to see the other hand doing something. Yes, she is sad, but what is the underlying emotion? If she loves one of these two people she could be hurt, angry, any sort of thing along those lines to give depth to that emotion. I feel because you were able to get the sadness in her, you are capable of deepening that emotion to make it more evocative. Having her hand splayed against the wall, for example, would give the impression of stress. Having her arm crossed in front of her would give the impression that she is comforting herself, denoting that she feels hurt. Visual cues such as these connect the scene in the room with the girl outside of it. Outside of this, I think her shoulders are uneven, our left (her right) one being higher than the other. Because her elbows are on the same general plane, it gives the impression that her shoulders would be pulled up to about the same area. The extra push up of the left (her right) shoulder just seems to obscure that she has a neck since it's up too far. :]

Very nice piece of work! I think it was very successful! Keep it up!
