Constructive criticism appreciated ^^
I found the background stock image on DeviantArt, I added some texture overlay to the top of the image, then added the ripple underneath where Michiru and Minagi are standing, I had to change the colours quite a bit to blend it in, I still don't think it looks quite right...
I then changed the colours of the render, making it softer, and also adding texture and a little glow. Then I added a little colour overlay to parts of the image. Thankfully my laptop survived and didn't crash!
I didn't want the end result to be too bright, and I decided to leave the water clear.
