Christmas card imagery - shapes

Creating the Christmas card imagery using a variety of shapes to find which ones work best and effectively for the front of the cards.

After my crit it was said that the triangle images gave a good subtle effect that the image was there, and also that the circles gave a better clean shape.
I will take this an combine the two ideas, in a way that the image is created from circles, but the image becomes subtle, but possibly using a slight change in tint.
