I think the photo which you posted probably portraying a girl trying to 'act cute' to apologise which turns out with a weird expression.
I went to multiply and browse through your album as well, most of the shots are direct shots which is suitable for Resume/NRIC application etc. It does not portray any meaning in your photo, just a direct shot, thats all.
Try shooting in different angle and different zoom and contrast. Can be improved further.
