Unfortunately had to watch some Star Trek to get away with this but here are tonight's efforts. Not quite the effects I was looking for from the Brayer but think it's because the one I've got isn't the right one for the job - but never mind good cards nonetheless!
The second is a free stamp set that came with a magazine (Simply Cards and Papercraft) which is Molly Blooms. Stamped the girl, then created a mask for the girl to stamp the boy in the background. Used promarkers to colour and then cut around with a border to create an outline.
For the background used the Happy Birthday Big and Juicy pad again but the blue end and layered up the card with a brayer. Then used some water to sprinkle, covered with clingfilm and wrinkled it to create the texture on the card.
When it had dried layered up the card and stamped Happy Birthday in a dark blue below the image.
Not brilliant - but nice cards none the less - and liked my little play tonight!
