Interesting peices, and I'm glad to see that you have the ability to focus on a certain object (YAY!) my suggestions for each one (If, you know, you ever want to be silly enough to go retake them :p)
Picture number 1:
Its a beautiful flower, and the focus is flawless. It breaks the rule of thirds, though. When taking a picture of this sort (Or any picture, really) it is extremely important to remember where the placement of the object in focus lies.
Picture number 2:
Again, beautiful subject matter, but this time it is both out of focus as well as breaking the rule of thirds.
Picture number 3:
(WHERE DO YOU FIND SUCH BEAUTIFUL PLACES AND THINGS?!) Gorgeous, though there isn't any interest to it. I would recommend putting someone in there to add interest.
Picture number 4:
Its interesting, but there is nothing abosolutely astounding about it. Cool tree, by the way. Still, there is nothing really wrong with it.
Picture number 5:
There is a little too much going on at once, and though the red object captures your eye, its extremely over powering. My recomendation: Stop and think about how you can have quite a bit of focus on the object and a blurry background. A slight focus on an overall picture is nice, a single focus on ONE particular spot is powerful.
Picture number 6:
FOCUS- YAYYYYY! Still, the part in focus doesn't really feel right sitting right smack dab in the middle and a tad bit too high.
Picture number 7:
Honestly, don't crop down the entire picture to the sign and some wood. It doesn't really look professional. Take a step back, focus, remember the rule of thirds, work around with angles, THEN take the picture.
