By no means do I recommend taking other people's ideas. It lacks the intimacy of a personal tattoo, and instead is just a "I got inked cause it looked cool." If you aren't 100% sure that you want the tattoo, don't get it. Get the Blockland B!
That being said, I don't see anything wrong with sharing what I intend to do and maybe that'll help with inspiration-
Im turning both of my arms into sleeves, with nature/landscape/sky and space on my right and armor on my left. But the little details will tell stories. Supposedly my spirit animal is a lion so my left shoulder was going to be a shield/crest covering over some chainmail. But below that I want to have an old pirate's treasure map (first college mascot was the pirates, sailing is a hobby of mine, pirates vs ninjas I always go pirates. I might've been a pirate in a past life for all I know haha)The nature side is going to have runes for the elements, a little camping scene that I might dedicate to my dad, an aztec-dragon styled ouroboros in the sky, some constellations in the space scene on my bicep, nebula and deep space (David Bowie on a rocketship? jk) on my top right. I might do some trippy geometric pattern (metaphor for complexity of the universe comes from simplicity? or maybe it just sounds/looks cool as forget. idk.)
I'll copy-paste my tattoo notes in a PM for anyone interested in full detail and tattoo examples.
OP seriously just think of something important and close to you. There's temporary tattoos you can get that are custom made to be like the tattoo you want. So you can see if you wanna make it bigger or change parts of it.
