The borders on all of them kind of kill the photos for me. The orange really just hurts it a lot, Flat black or white borders go better most of the time IMO. Try to work on your coloring in the post work next shoot it's kind of i don't know really its just... Well i dunno just work on it a little more. Sorry if i don't word things right I'm having a blond moment and can't think of the right words.

1. Cool shot looks like its rushing water but kind of hard to tell, could just be icicles lol. But looks odd kind of half blurred in the bg and the coloring on the grass is weird the way it flip flops.

2. This is probably my favorite of all of them. Work on your angling. I think it would have been cool to kind of get underneath it more and shoot from that.
Also try to use diagonals. It usually helps a photo to get some diagonal shapes or lines going.

3. This shot is a little bit to distracting by the bg for me. The church seems to be the main focus of the photo but you named it graveyard. So maybe if you got in closer and took a photo more of the graves and less of a landscape of the church area.

4. This one is a bit different. Everything seems to be pretty blurred except for the leave which takes up a very small portion of the photo. Maybe crop is smaller? I definantly like the view o the city in the BG though that looks really cool.

The lighting could be a bit brighter on a couple of these (but thats hard to help outside) what ISO were you using? It might help a little more to use a higher one like 300-800 though that might be too bright or dark. Also for the leaf photo a macro shot might have been cool. Your camera might have it, the icon for it is a little flower looking thing.

Hope my criticism helps a little more.
