I made this picture in Illustrator. The stars in the background are created using Astute Graphics space fill tool which allows you to quickly fill an area with randomly scattered repeating shapes. I saved out the picture as a jpeg and dropped it into PhotoShop. On the layer below I pasted some paper texture clip art and I changed the blend model of the trees layer to multiply. Ta daa! To finish off a added a little vignette then posted it on my Instagram channel.
