wall tattoos for youth rooms

hey,
I am in the process of renovating my youth room and found these 2 pictures on the internet that I really like:

my question:
are these possibly wall decals or simple drawings?

best regards

I really like wall tattoos, especially since they are really easy to remove and look great, the only thing that still bothers me is that most designs are extremely cheesy. I hope that changes with their popularity... ;)

Unfortunately, I don't know where, but I do think that it involves wall tattoos. But you could just make it yourself, right? Print out these pictures enlarged and cut them out. Then stick them on the wall and outline them with a pen. Just color the part in the middle ;) It should spark something, right? And it's cheaper for you.
