sorry, don't want to seem to have always put my "senf dazu" ( German expression of posting an opinion whether it is asked or not, like "to put in one's twopenn'orth" ;-)) but was reading in this forum for a bit and at least tatoos are a thing i'm quite in to because I'm thinking of going further with mine. Fore my opinion a tattoo or the motive should fit in the symmetry of the bodypart. So if you thinking of doing the moon and elf thing ( compliment to faile for the drawings! ) I would suggest the right shoulder blade and don't make it to small! And an other advise ist: be aware of that tatooing can be addicted, so be sure that you can go on with that motiv later if you want to expand it! That why I stuck in the moment with mine :-( Because I made me some borders and don't know yet how to integrate them in to a larger one with out getting to many several pices ( I think you'll look like an pinn board if you got to many different pieces without an context )
