I like the repeating patterns in the last two and the textures in all of these. Number 5 is my favorite, though.
i really like #3 and #5. #5 looks like a surrealist painting in a way.
The colors and vintage feel make number 3 excellent.
LOVE LOVE LOVE the colors of the bikes.
I love the doubling in 4 and 5. I like the colors in 4 and the shapes in 5. Sorry, I can't choose between the two.
The first image reminds me of a Robert Adams composition, cut right in half with a lot of sky above the building.
I like the fact that in #3, your eye is led, though not immediately, to the price tag, which allows you an instant contextualization of the image, which up until that point is not, perhaps, immediately clear.
Love the lines and the color in 4
The bike rainbow, that's a great image. These are really diverse and great.
I like the one with the guitars because the shapes are really interesting
