Great set Chris!
Closed: I think this image works very well. The subtle, complimentary colours are really nice, and the colour pop suits the subject nicely - though you missed a few buds bottom left near the leaves!!
Snappers choice: All are really nice, punchy images that have certainly benefited from the colour pop technique.
My favourite is the first image, which I think is fantastic! The composition is excellent, and the details and contrasts in the B&W areas are great!
The bold, yellow works very well against that terrific moody sky! Cracking image with superb impact....just what
'colour-pop' was invented for!
