When I saw this layout challenge and the circle it made me want to use the medallion stamp in the background. I used the rock and roll technique when I stamped it.
I found the colour challenge to be much more difficult. I rarely use creamy caramel and find it to be one of the more unappealing colours. I just used it to stamp so it wasn't that bad. In the end the card is interesting and one I never would have come up with without the challenges and that's what makes them so fantastic
