1) I made the levels highlight the some edges of the water, blurred the background, and had the vase become black.
2)I like that the where the water splashes out there's drops flying to the side that you can see, and that the water is black, but the edges are blue so you mainly focus on that.
3) I would change the color of the water inside the vase since it practically gets sucked into part of the background.
4) I used the coffee shop vivid action, and changed the levels of the picture.
5) I like the windows picture because I got my picture at sunset and there was trees in it to and the way i photoshopped it looks pretty cool
