A bit too colorful, I would say and as for the subject - A cemetery can look nice and peaceful if it is covered with grass and flowers. Your title could have been a bit more subtle.
Can't help it, but it's too colourful for me as well. To me is a graveyard a place of rest and peace. I assume that both your title and chosen colours show no (or too few) respect to those who are laying there.
I would have to agree with the above comments...a bit too colorful in my opinion. I think that if you desaturated the colored image, and then added in selective color to parts of the photo, it would have provided more of an impact. But by all means, keep experimenting! :)
