One of the ways I pose very quickly are through tricks I've developed by trial and error. If the relationship between the lamp and Sophia is giving you fits, then try this: Place the lantern to its desired location in the scene. Place Sophia roughly 50 to 75 away from her final position in the render. Position the joints in the arm (shoulder, arm and wrist) so that they look natural, and having the hand at the right height to hold the lantern. As you do this the elbow will try to migrate out into an unnatural position (rotate is your best friend to correct this). Once the arm position looks satisfactory to you eye's intent, simply move Sophia to the lamp. Some minor tweaking may be required. This approach has saved me enormous amounts of time, and has given me better results. I hope this is helpful to you.
