good websites to find sun,moon,star, and butterfly tattoos?

ii want a tattoo, and i’ve looked around but ii just cant find one.

You don’t need to look for existing tattoos. You don’t need to go to tattoo sites.
You should find any images, from any source, that appeals to you. You can draw something, you can take photos, find pictures, look in scrapbooks, the library, the net, look to nature, look in magazines, look in art books.
Find something that you haven’t already seen in a tattoo. Then add to it, adjust it, put your own colors in it, put personal images, symbols, stuff from your thoughts, your dreams, etc.
Then take everything that you like – maybe a little from this, and a little from that – and go to your tattooist (licensed, reputable, and an artist whose work you like), and let him/her work out a custom tattoo design.
You say that you have looked, these are not uncommon images, … so give it another try, and try to see through different eyes.
good luck
