I do not care for the oversaturated, brilliant colors with fluorescent dye pigments pitted against the natural earth tones...it looks very jarring and trendy, in a bad way. Same with the orange scarf and the traditional overcoat...bad match from my perspective.
There's more good here than bad. Everybody has his/her opinions. Mine are mine. I do not like the figure/background attachment with the small tree sprouting out of her shoulder in the "tractor" shot. (it looks more like an old grader or buck rake than a tractor...). I am intimately familiar with those old metal seats--they are comfortable and iconic, and they really,rrrrrreally say "old-timey" to people who have seen them and been around them. The barn and the fence look very old. The OOF grass in foreground is a bit distracting, and I dislike the amount of depth of field behind her...the tree and its small branches are rendered in too good a focus. I wish this had been shot with a 180mm lens or 200mm at around f/4 instead.
Shot #2 is a nice over the shoulder look. She looks very pretty in that shot. I'd be tempted to clone out the dark branches at 10 and 2 o'clock, to clean up the nicely OOF backdrop. Nice to see a bustline, but the grass seed head overlapping the bust is distracting. Goood pose for a senior girl. Her under-eye lines are a bit prominent, might want to touch those up a bit.
Shot #3-You have a great situation there, since it is actually raining pretty good. I wish the tilt were not there, I dislike tilt immensely. I think if you had kept the camera straight up and down it would have improved the shot by getting in more of the dark background and the atmospheric haze/fog/mist, and the sapling tree on the left would have echoed the corner fence post with two uprights, with her in the middle. Would have been nice to show that rain streaking down with a slower shutter speed, but then, there's those doggone power lines in the background....#3 has a beautiful full smile, a lovely angle to her face, and excellent rapport with the camera. I just hate the tilt...showing rain like that can be very hit and miss...needs just the right shutter speed for the drop size and frequency,and it might only last for 1-2 minutes, then stop, start,etc.
#4 you have backed up,and now those doggone power lines intrude....I'd loved to have seen that one shot with a 300mm f/4 lens, with JUST the top of the barn and a little bit of the hills as the top of the frame...lens focal length looks 85mm-ish or so, and the angle of acceptance behind her is too wide for my taste--she's too small, and there's too much background for my taste. I would have loved to have seen #4 done differently, mainly because the power lines kill it for me. The top of the hill behind shows the fog/mist/cloudy skies...this is an environmental shot, but I don't like what the lens reveals about the environment...I like the grasses, love the barn, sapling, but hate the wires...
#5: I like the way you use the technique of skimming, which is aiming the lens down the side of a wall or building, to use the wall as OOF foreground that leads the eye right to the subject; with that OOF skimmed wall, the orange scarf is totally redundant,and just gaudy...
Man, that might sound brutal...I hope not...just one guy's opinions.
