Now human brain is most advanced shape recognizing engine and that is why you can see million of things in these shapes: drag them, transform and warp: and there will be plenty of silhouettes to see there.

Moreover you can cut the parts of the shapes to create some elements.

I will try to explain this in more details - I will make a selection and copy it to a new layer.

And another one:

Combine these shapes with the one that looks like a fish - on the top down part on the image.

So I think you got it. I recommend you to practice any application that comes into your hands because in digital world t really matters.

I add some design elements to my character but this is off the topic now. I'm using some custom brushes I have in my set.

SO here it is. I hope you got my idea on this. I really don't want you to follow exactly my steps because you probably can make something more interesting if you spend some time. This was a tutorial how you can use such application as ALCHEMY to visualize, create interesting shapes and use them in your concept art and production. I'm adding the shapes I've created so you can download them and practice.
