I think this will be my favorite drawing ever! But when you look at it, it's like they are smiling for the camera. Even though I didn't purposely drew them like that. But still, it really looks like they are smiling for the camera.
The one on the left is smiling while facing the front like she'd gladly take a photo of herself and on the right looks like she wanted to avoid looking at the camera while smiling.
Don't you think so? ~('w')~
