I put references to my the post for the previous lecture so this post will focus on the other items in the scenes. The two biggest will be the grass in front of the rock the bunny is on and the rock itself. The tulips and fern will be background and a little out of focus when I apply the depth of field. Unfortunately I did not have time to go out to woods and take pictures myself but I did find these images on the internet and the should do.
Grass
Rock
Tulips
Ferns
And as a reminder here is my bunny reference.
