Alright, I'll bite. I won't C&C your whole photostream, but I'll do a couple.
I don't know how much aperture control you have on a coolpix. The second one of the lily (Sunset at 2) has potential. Needs to be stopped down (smaller aperture, larger f number) to help with depth of field to keep the stamens in focus. This might require more light to pull off, but that's not a big deal.
The "I love you edit" also has potential in my eyes. It didn't need to be edited, it needed better light, although the edit gets you some of the way there. In the original the light is very flat. If you'd set a light in the direction of the upper right corner you would have gotten a much more dynamic look.
