Project - I think the crop works better as others have said. A nice photo capturing real life, a nice find as this totally captures the project theme.
Film - Nice take on the theme, I thought of getting the interior of a cinema but getting a camera inside is impossible because they don't want people recording films

. As someone else has said I like the composition, I like how the vertical lines of the right hand side of the image and the roof of the building follow the frame of the picture. Nice shot
Dirty - I really like this shot, not something I would have thought of (I wish I had!). It really sums dirty up for me in many ways, I personally don't like smoking and so thats one element, but then the ground and packet are also dirty.
As others have said you're adventurous and are getting out there to pick up your shots, I like this. I haven't quite found the confidence to get out there in full view of others, its a weird 'what will they think' feeling even though I don't know them. I have taken some outside shots, but hopefully one day I'll have your go get um spirit! Keep it up and I look forward to your future images.
