This is a wonderful image. Here, you have that innocent "school-girl" aura about you and in the "Simply Me" image, you have that mature, sophisticated look. So, are these the real two sides of Monica? :-)
I love the empty concrete forground and the general composition. I can see why the lighting situation caught your eyes, it is very fitting for this image. All the lines work really well, the bars of light, yuoself and your shoes with the shadows. I also like the soft slightly oof focus feel and that you didn't try to sharpen it into focus.
Good job.
I lie how you are staring right at the camera, maybe try to lighten your face abit, but I also like that since your frustrated, that it is out of the mainlight.
I agree with Shannon, very cute. :) I like the strong pattern suggested by the lines, as well as the textured column, and your sullen look with face in shadow. Nicely done.
The lines really make this interesting. The shoes (ha, Nixter) give yet another diagonal dimension to this as they parallel the shadows from your legs(and almost evenly space with)...way cool!
Wish you'd had a better day, and hope knowing several of us like your image helps a little. Besides, you've caught a shot I've wanted for a long while - diagonal lines. Thanks for the inspiration!
