Cover Redesign

WIP -

One of my main goals where I work is to redesign all the catalogues, creating an image that's coherent, which is something they never had.

This is what I came up with, under some constrains: it had to incorporate a color code for easier identification, but at the same time it needed to portrait sobriety. The current cover is too dark, but I also needed to visually distinguish catalogue from price list, so catalogues are in this dark grey color, while price lists are in a light grey color.

Right now, I fear that the background image is too strong and that it takes attention from the actual product.

What do you think?
