Time for a hybrid approach, methinks...

As usual, I went my own way - the image is on a decoupage sheet and although I did a bit of minimal layering on the karate dude (main image, layer that's jacket and head, separate belt) I ignored the main backdrop and cut my own circle from red card, inked the edge for depth and added a big, hand cut number to tailor the card for the recipient.
The image is pre-coloured (although I did add a bit extra shading with Copics, particularly on the belt) so it's just the cutting out that's time-consuming here.
It's always harder to impress a seven-year-old than his parents I reckon - the card was declared "cool" so I think making it hard on myself paid off!
