Wow, I took an exact looking photo of this church last week!

As for your picture, the halos around the two crosses are quite irritating. The ground is a tad too dark and I think the sky isn't very appealing. I like how your picture is taken from a higher vantage point than mine though the road doesn't help the picture.
If I'm correct that you used some dodge and burn, I'm not sure how well it works for me. I really like the image and can see what you were doing but for my taste I prefer to see it used as an enhancement.
your processing is a little too evident for my tastes.. (and yes, I have photos in my portfolio that are exremely evidently over-processed.. so I'm not saying that you *shouldn't* be doing it.. I just hate seeing it in challenges, personally). Just a suggestion.. you might want to start learning how to layer mask.. it can really make a difference in getting rid of the halos that dodging/burning can cause (or other methods). I don't know of any tutorials off-hand, but do a search up for layer-masking or similar words on google, and start experimenting.. it's fun!
