Vector (?) for sale

.
While randomly searching for vector images at work, I saw this nice simple design of colorful clouds on top of one another. The picture was for sale however (yeah, for what ever purpose it may serve. XD) so i tired to imitate it by doing my own version c/o Photoshop!

See that colorful cloud on the lower left?

That's the one I tried to pirate.

The result?

VIOLA! XD

...Now i just have to find a way where I can sell it too! LOL!
