Nice juxtaposition to get the size illusion. Exposuer is substantially too dark, and you could benefit from better lighting, but it might be difficult to retain the illusion.
good job capturing something more than just "garbage" while keeping the focus of the image on the garbage - stunning sky, very nice layout or crop, good work :)
The sky is very nice in this shot but the foreground with the garbage just doesn't work for me I would have liked it if it were lighter and I could more clearly make out the grapette, I feel there is not enough contrast, maybe by highligting the lights and darkening the darks it would have brought it to life.
