Purrfect Kittens

My friend has two black cats, one short hair and one long hair. I have tried to recreate them on this card but they do look very dark in the photo where as in real life they are more dark grey than black.

Images: "you're purrfect" Clearly Besotted
Paper: "snap" Simple Stories
Sentiment: Papermania but not sure what set
