So .. you wanted a critique... let's start:
Pic. 1:
Very nice contrast and interesting composition, however I'd like to see the whole calculator on the right. But ok
P 2
Falling on the left side? but nice reflection in the water
3
I really enjoy it, but if you can go back there... try to take the texture of things in the bottom in focus. we will see the effect
4
Great drops!
5
I like it very much. I like the croping and contrast. It is the picture *with soul*
6 and 7. ok for me. I won't comment the the topic because I have nothing in common with Americans so I don't care.
8.
Great reflection but for me too much blue color. maybe improving in ps?
9. and 10 I like them. Great idea.
