all right, well im no photographer, i have taken a photography class in college and Graphic design does deal with initial set up like in photography. here are some thoughts.
-well number 5 is definitely your best
- all or most of your photos have the central focal point as your "friend." this is a common beginner set up, but putting the main "thing" in the dead center is often considered boring, try placing the main focus slightly away from the center.
-negative space (background space) the background is just as important as the foreground. In no. 7 her head is placed a little high making the negative space awkward and the focal point is her neck. Its all about balancing out a shot, say the majority of the "thing" is on the left, then the right side background must have something that balances it out (other thing, space, something to balance it out)
- Lighting, lighting can make or break any photo... overall you did really good, just know at all times where your light source is and what it is focusing on. (also where the shadows form)
-these are the major things that people often forget or overlook so remember these they will make all the difference.
-overall A grade, your pics are good, things that should be in focus are and you illustrated great poses from your "friend". Your by far above the level off most people, but keep at it even the greats find room for improvement.
Like i said im no photographer, but these are some major things any professional will take into consider when critiquing your work.
Good job
