(I'm making an attempt to explain why I give any photo 3 or less. Obviously I won't like these photos, but DPC is a place to learn a) about what works in this environment and b) about what other individuals think. Please don't be despondant just because I don't like your shot. Rather than that, if your entry scored low, please try and understand one commentor's reasons.)
Of all the 3s I gave out in this challenge, this one caused me the most grief. It's not that bad, really. The colours are vivid. The composition is dynamic and the challenge has been met head on. I scored low because the subject is so depressing and unwelcoming. I know that that's your point - the end of summer exemplified in flowers. But it turns me off. Also your fillflash worked well ont he top flowers but not on the bottom one, and it created a harsh shadow inside the structure.
