smallest tattoo size

Ideas for a feminine tattoo that shows strength (medium to small in size)?

Im getting my first tattoo at the end of the summer (im 16) and I want it to symbolize strength. Im not allowed something huge so on the smaller size would be awesome. Also, im either putting it on my shoulder blade, neck, or foot if placement matters

I want something like this
and I dont think its stupid cause to me it shows religious belief
