Rebecca by LauraHince

Both are good pictures for me. Photography looks good. The left hand is maybe a little over exposed especially on her hat where detail is starting to be lost. High key effect looks good on face but not hat.
I like these images although like Paul not totally sure as why the two are combined. If there was more clothing in the left it would make more to me.
In my mod I've darkened high lights a little on left hand image and lightened the eyes. You can see the blue more in the mod.
You have in my view an interesting style for showing young fashion.
Good work,
regards
Ian
ps I don't like green shutter very much but maybe best plain background available.

Rust ... by Sone

Interesting image but a little difficult to interpret. ~I think you are saying the numeral 5 comes out of the rusty chaos.
If that is was you mean then the 5 could be better placed in the frame rather than touching the edge.
The photography and settings look fine with f5.6 giving you a limited DOF. you could have used ISO100 and 1/250th but would not have made much practical improvement..
You should consider that the image does not say much to a detached viewer like me but may be suitable to illustrate the topic set for your homework.

Bedruthan Steps - Cornwall by hallettm

A good capture with an early morning sky. Well worth getting out of bed for. The sun is not reaching the cliffs so the warm light is mostly missing.
The slow speed has created an interesting milky look to the sea.
It does not look very sharp on screen in the small pixel format, maybe needed more sharpening after re sizing for up loading.
I've done a mod where I've darkened the high lights to bring out sky . The sky still looks light, was the filter a grad or just nd to slow the exposure?
I also sharpened a touch.
Composition is good, using a wider/shorter lens length would have included some framing cliff on the left also but maybe sky was less interesting to left.
Nice one,
Ian

NATURE'S GIFT by ukgubbi

Good capture. A charming picture of children enjoying life. As advised above a touch of fill flash would have helped exposed the boys more.
I've done a mod also:
I used photoshop to lighten shadows and darken highlights followed by burning midtones in areas away from the boys, I finished with a touch of sharpening.
I cropped from left and top to achieve a more balanced feel. I like the tree on the right as I feel it frames the images and helps sets the swinging from trees theme. My cropping of some of the bright sky helps the eye see into the darker more interesting areas.

Castle Sinclair Girnigoe Caithness by ErictheViking

Good one. Successful image although the bridge looks more sharp than castle to me.

Pay And Display by Valveman

Well spotted.

Steps by KurtSkeels

Interesting picture showing how a mountain landscape can be changed (spoilt?) by man, worse than Snowdon or parts of Lake District.
Well composed showing foreground, the steps, cafe, glacier and valley town, plus people to add scale

Stac Pollaidh Reflections 2 by briantjjones

Good image, well composed. I feel it maybe should be a little warmer as it was shot just before sunrise. My view of course, you were there?
I've done a mod which is just a suggestion, really it's down to personal taste.
I've warmed the image and darkened the highlights and mid tones, plus a touch of sharpening.The sky looks more interesting to me.
regards

That's an old commie thinking,
