My sister asked me to design the tattoo she's getting this week and we thought of a jellyfish attacking a building.
There's a meaning behind all the tattoos she gets, and this one has something to do with her switching majors from engineering to marine biology. Or something. There's more to it, I dunno I'll have to ask her.
She asked for something sketchy and charcoal-looking, so this is what I came up with.

Heee.
