Nowadays people incorporate different patterns in the one tattoo design. Crow tattoo pictures are great example of this incorporation.
You rarely see the crow inked separately, it is usually depicted with other meaningful patterns that let the design be unusual and much more interesting. The most popular patterns emphasize the main meaning: skull, dedications, roses, sun and much more.
First of all, you should choose what the crow tattoo means for you – and then you are free to add other patterns to make it really outstanding.
