I'm really falling in love with geometry overlaid photography. Such an elegant design concept. This one I like more than most I've seen because the graphic shapes almost become part of the forest itself.
Black n White photos layered with coloured geometric shapes creates a really clean, yet visually pleasing image. We could create quite a busy image or keep it quite simple like this and sit the logo on a coloured shape.
I really like the way the colours subtly compliment one another and the way the lines create different vision paths across the image. Your eyes are lead one way and then carried another creating individual journeys.
