My Self Portrait.

Instead of doing a self-portrait, I want to do a portrait of my little sister. I want to do it outside somewhere, maybe around alot of trees or a field with lots of flowers.I have two different ideas for it, one is to do a close up of her face in some flowers. The other is to have her sitting or just wandering around aimlessly. I want to take the picture around 10 ir 12 o clock because thats when the sun shines the most and i want the picture to be very bright.
