I couldn't make a tutorial because Fraps didn't want to work and I didn't have anything else, just keep practicing your poses, you don't have to post every pose you made, I posed for a total of a year before I got extremely good at it, and I only started posting my poses this year, 3 years after I got good at it.
Posing takes time and a lot of practice due to the bullstuff limitations the Ragdolls have, but after a while you can pick it up.
