C&c
AHAHA Music factory lol.
C&C = Comments and Critiques.
This belongs in the Digital Photography section...
That being said
Photo 1 - No focal point. I don't know which part of the image to look at, it looks like you just pointed the camera at some grass with flowers and clicked.
Photo 2- It does look 2d like previous poster mentioned. Try shooting from a bit lower, so you are shooting diagonally rather than straight down. The patterns of the flower and the background clash and are hard to look at.
Photo 3 - Not much to say about this one, looks like a standard snapshot of some girl taken inside with the on camera flash.
Photo 4 - This is my favorite of all of them. Would look better zoomed in more, or cropped tighter. I'm guessing you took it at maximum zoom from the 55mm, so zoom with your feet or crop it tighter. It is also centered, and centering is, for the most part, a big no-no in photography.
Keep taking pictures, you will learn more from trial and error with yourself than you will from any of us 🙂
