Swim

Hi, the next topic from Illustration Friday is about "Swim".
Personally, I don't know how to swim but I really like the beach. Especially, I like scuba diving that I can discover the world of underwater. 
This time I tried to use gouache paint for my artwork.
I researched some images on Google as well.

 

First, I did draw a thumbnail of a turtle and tried to use a gouache paint on it.

Second, I painted the actual artwork with the larger size.

Next, I placed my artwork in Adobe Photoshop to adjust a little bit color on it.

I also added an ocean background to fit with a turtle. I changed the blending option of a turtle to hard light as well.

Then, I used rising sun brush to make an effect on my background.

Finally, I added some underworld plant and fishes into my artwork to make a complete version of my design. 

This is my complete artwork.
