Male birthday cards

I have a Male stamp-a-stack on Thursday night (still a few more places if you'd like to come along!!) and this is one of the cards I will be demonstrating! The image is from the groovy drawn set called Need for Speed. I've stuck to blues and greens with some of my fav Grey in there too! The way I've done the background is just by stamping the ink pad directly onto the card stock, you can make as much or as little rough looking marks as you wish! I love this technique as it's sooo super easy! Male cards can be tricky to make, how do you do yours?? Is there a favourite set that you turn to??
Love to hear from you, hope your weekend has been super, thanks for popping in!
