I like the way you have laid this out..it`s busy but it works (at least for me).
Lots to keep the interest and very fitting for the theme of the challenge.
Well done
God this is a great collage! I am torn: knowing that digital is the higher tech and film the lower tech and yet technology seems more 'gadgety' to me. Cannot fault on subject matter. The artist here has evoked lower technology and done so in the most devious of ways. I love the dof, fades on the corners and full background, excellent sharpness on the canister and central environment. A cacophany of tiny different textures that all blend into a whole that draws the piece together. Very nicely done.
