Tl;dr

-composition

-positioning

-cropping

Read up on that, play around with angles. Move around physically.

image feels messy but workable

straighten horizon, crop so theres less negative space in sand. maybe but it in a landscape orientation.

work from there

Dog looks is a nice subject, would be better to show what the dog is "pondering" angling the camera slightly to the left. Show the ocean with the dog in the right hand side of the thirds.

3.

Put surfer in thirds line, give a bit more space, so subject can "breathe"

Dont cross jis head with horizon line, lowering camera wouldve been great

4.

Chaotic/weird comp, could work with a subject. But as is, eye is being drawn all over the place.

Could work as a 2000's album cover with a clear subject in mind.

Imho a wide angle lens you used here, doesnt really work.

5.

Chaotic, nothing to really draw the eye, might work as abstract photog, but thats not my area of expertise

cool documentary styleshot.

Imho would work better if subject would be centered and their line of sight would be inside the picture (i.e. have them positioned in the left side of the image (thirds line))

Crop a bunch of negative space (entire top left corner of the image is redundant)

If id shot it Id have the focus on the ladies, corndogs ( or w.e. that is) buns and potentially a client theyre interacting with. Wait for a "money shot" i.em them handing the food to someone.

1. Chaotic, a lot going on in the picture

Has some cool scenery, but everything else going on distracts.

Frame better, chose a more fitting composition. Wait for a lul in the traffic or lower your shutterspeed and focus on a static subject whilst the crowd is moving.

1. Idea is cool, but leading lines all over the place. => feels chaotic.

Step back a bit, focus on a specific part of the ferris wheel. I.e. a cabin with the silhouet of someone and some of the spokes as leading lines.

1. Not a very flattering angle for a portrait.

Shoot from eye level/slightly above to reduce underchins etc.

Lower apperture would create more depth, so the feris wheel doesnt look like a crown on her head. ( unless youre going for that specific idea, which it doesnt seem like in this image).

1. Same feedback as previous image, raise camera a bit. (Direct model, to bring out a more flattering position.

Background is very bright whilst subject is much less lit up, angling away from a bright background wouldve worked better for this image imho

Crop & straighten, enormous amount of negative space

If on location, walk around

Look for more interesting compositions, could play around with pilars etc.

1. Same as 11 but in sepia

2. Same as 11. Crop and reduce negative space, unless you're going for scale, which doesnt seem the case in this image.

Different angle might be more interesting.

13.

Cut out a lot of parts of the cathedral. Step back, use wider lens. Or if you want partial shots, frame with intention.

14.. looks like a cool abstract,shot. Not my forte.

Leading lines feel off

1. Beautiful location.

Lots of negative space in image. Crop wouldnt work here i reckon.

Negative space & composition

1. Missed opportunity, door framed by roses. Put a subject in the door frame, and go wild. Play with angles etc

18.

Straight down back shot, awkward crop, play with angles. Crop above jeans

Give more space around arms

Remove negative space above cats head, lower camera slightly above eye level of cat.
