I am having such fun playing with textures!! If you want to pick up some free textures, head over to Kim Klassen cafe blog. She recently gave away 12 free ones as part of her 12 Days of Textures. She has tutorials on there as well to walk you through how to blend them into your photos.
This one took awhile because I literally had to go back and dodge/burn the texture out of the branches, zooming in 400% sometimes, but I think it was worth it. It takes a dreary afternoon and makes it shine.
