We should be able to add multiple tattoos to body parts in Skate.

The simple small tattoos and limited to 4 (1 per limb) is a big disappointment IMO. Adding the option to add as many tattoos as you'd like and layer them is a very easy thing to implement and will give further creativity to the player as far as character customization goes. I hope this gets added in the very near future, if not the next minor update.
