Need some advice/tips

Ok so I need some help... my bf is on a trip to LA with some boys for a baseball tournament and I wanted to send him some sexy pics to tease him a bit since he did that to me a few days ago and I couldn't do anything about it lol but I rarely do it and I honestly have no idea how I should look in the pictures or if I should show my face?? I have no idea and need some help! lol anything will help.
