There are a ton of pose packages out there both free and for sale.

Do a search here in the free area and in the market place for "pose"  and you will find several dozen pose packages.

Also Daz has a number of pose packages too.

You can also find more free ones by searching "Pose" at this link:

Poses can be used cross figure with just a bit of tweaking sometimes.  Currently I'm doing some renders of Aiko and I'm using poses for Teen and V3.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
