This is a lot of information and takes awhile to learn all the aspects of adjusting things in Photoshop and using textures, but thought it might give you something to think about! Sunflowers make great subjects. I had the idea of lining these up, but had to use a little ingenuity to get them to stand still. With water bottles stuffed with paper towels and other “vases” I could get them as I wanted against a nice green wall. The original image leaves a lot to be desired!
Then sampled the green background and painted over the vases, leaving the glass at the top of the far right vase.
I added a blank layer and used the clone tool to paint the top of the vase into each of the other flowers.
I lowered the opacity of the blank layer which now has the 5 vase tops to about 70%.
The Text Tool gives you a new layer and I typed Sunflowers in Castella… adjusted font size and gave the space between the letters (called Kerning) a little more room.
Added the Cinnamon Texture from Kim Klassen’s collection… used the Hard Light Blend Mode in Photoshop.
Finally I felt the green background (which actually has more yellow in it) needed some tweaking, so I made a selection in PS using the Select > Color Range and got most of the green included… using Layers > Adjustment > Hue/Saturation and using the sliders for yellow, I was able to get a color I liked better which also makes the sunflowers pop!
