I have no comment or criticism just a question. Why are you posting these in the noob section? You may be a noob to this forum ( as am I ) but you are obviously not a noob to photography. These are fantastic.
The PP work looks pretty sloppy on #4, you can easily see the lines between the lower legs and the background.
The sky in all photos look a bit odd...almost like they were slapped in from another photo...or at least a lot of selective editing which makes the photo loose depth.
