Number 1 and 2 are my seeds selections from source image.
Number 3 is how I put together different sizes and shapes of seeds to create the shell. Used warping, resizing and flipping horizontal.
step 2 of 3
I used the image of two turtles and added the created shells on top of them.
I colored the whole image slightly by using a gradient adjustment layer.
I calmed down the tones (hue/saturation), added lights, gaussian blur, added shadows around the whole image to create the feeling of spotlight.
And also added brightness/contrast adjustment layer.
