To the OP (sorry, I just can't bring myself to call you Buttkicker
)
A well spotted shot
By your own admission it was a quick grab shot and there are plenty of flaws, however, it's clear by this thread that it's provoking some emotional responses and that's what makes it a good shot IMO.
If it was a baby dressed for Halloween as a cute little pumpkin then I don't think the shot has enough technical merit to stand on its own, but the subject matter and the realism of the make-up has the shock factor to draw viewers in and make them react.
I think Janice hit the nail on the head when she said "we are not programmed to see a baby in this state and just think "oh, that's a bit of fun""
With all the focus being on the subject here, I really don't think that posters are giving the OP enough credit for this photograph. Putting aside the fact of the mother dressing the baby up, he spotted the opportunity for an emotive, unusual shot and he took it.
Context has a lot to do with it too.
The image wouldn't have drawn half as much attention if it showed the mother and baby in the middle of a crowd of other "zombies", (adults
and children) all dressed up, laughing and having a lot of fun . . . although that was probably the reality of the situation.
I don't know if this was a deliberate decision or just good luck (grab shots are often like that) but the OP has isolated the subject from the crowd and taken away any contextual cues. He's also managed to catch the mother with what could be interpreted as a menacing expression on her face. IMO these are the 2 over-riding factors in provoking the reactions that he has . . . and they have everything to do with the photographer rather than the subject. So for me, that deserves a "well done".
