Sweet Pea?

I am trying to design a tattoo of a sweet pea for myself, but I'm not sure exactly what they look like. I mean, I KNOW what they look like, but I can never find a clear picture of the leaves and how the petals are exactly shaped. Are there any sites that show the petals up close and leaves, like an informative site on it, not just how to grow it.



What do these mean?

" The leaves are pinnate with two leaflets and a terminal tendril, this twining round supporting plants to help it climb."



What does Pinnate/leaflets, and terminal tendril look like?
Sweet Pea?
these photos may be helpful for the tattoo :)
