Recently I have been using Pro Marker pens and using digital image  graphics for my cards. I also use Spectrum Noir pens these work well with the pro markers. This card I made for a friends birthday. Using 8x8 size card and backing papers cut to slightly smaller. I used same range of colours to match the image colours. Adding floral leaves die cut and paper flowers. 
I love greens with pinks seems to set it the image off pretty well I thought. 
Happy Crafting
