Sorry for your low score. I gave it a 7. Obviously I am in the minority. I think it was your subject that displeased people most. I would have scored it higher if it was a bit more exposed, but I think it did a good job for the challenge. I hope you do better and don't stop shooting.
It's a good concept and it's well shot, focus and exposure wise! I might have been tempted to add two 'fake' antenneas sticking out of the right corner of the photo to add more impact :)
It is indeed a dead end. The photo isn't very interesting to me though. Placing an ant or two (or whatever kinda bug it is for) in the photo would have made a nice impact though.
"Gets the Bugs Out" I love that it is simple but it also seems ill-placed. Maybe a closer shot of just the top where "Combat" is written or using rules of third for placement. Otherwise the shot is in focus and well done.
