This area as it shows the rails coming out of the over grow, plus it has neutral colour surroundings which will make the red clothing really pop!, and it's a great wall in which to add "50" to it.
I love this image so much, it says 'there is hope for this garbage'. The green grass and the open air give a more natural look. As if it looks like the charity is helping lots. Note the rails again (look great in this area).
And finally this one, i would shoot this with a little less light, It looks troubled and confusing and very stressful (as if something is taking over someone's everyday lifestyle; heart disease), i want to represent the disease as strongly as possible here, whilst expressing the charities help and support through the red garment.
