|No person and no cropped head... so DNMC :( 4 otherwise, -3 for DNMC = 1
Had this been a statue, it would not be grounds for a DQ. If you removed your son's head in Post processing, then that would be a reason for a DQ as that's not allowed in Advanced Editing.
Regardless, since it looks like a statue, you're going to get people who, like me, think it DNMC because it appears to not be a real person. But even it it looked like a person, cropping the head should be cropped by the frame, not edited out or hidden.
I will say if you took this shot like this without Photoshop trickery then VERY WELL DONE! :)
Hope this helps.
