grad photo casual poses.

In about three weeks, I will have my graduation photo pictorial already. until now, I'm not decided on what to wear for the casual photo part. and significantly, I don't know what my poses should be. Believe it or not, 20 shots are needed. so, can these poses already suffice?? 

GAAAAAHHH, still need to think of 11 poses still. :| wish me luck, okay? :)
