Halloween Playing Cards

My playing card project for my desktop design class.
For this project I was to make a matching set of playing card designs. We were required to make designs for all 4 face cards and 4 number cards. I didn't need to make it all for 4 suits, just 1. I would like to get back to this sometime and create the entire set if I ever get the time.
Also wouldn't be sure if for the other suits I should just make different monsters for the face cards or just make some minor tweaks to the pre-existing ones.
