My New Tattoo [Stencil Mockup]

This is a stencil mockup of a tattoo I'm getting soon. It's an endorphin molecule. Pretty sure it's going to be in greyscale, but thinking maybe making some of the atoms dark red/blue/violet? Otherwise the atoms will be different shades of grey to represent what kind of atoms they are. The only for sure changes will it'll go 20% bigger, and the front part will be reworked a little so that it takes up more of the chest and looks like more of a straight line.

Thoughts? Constructive criticism? Artistic direction? Different part of the body? I've played around with the idea of it snaking around more, but I'm liking the way it runs along my shoulder blade and back, so I'm not sure if I want to mess with the orientation much.

For now the molecule itself will get done, but I'm thinking, perhaps in the future, of putting in some shading or images. Although some people think it kinda looks cool just on it's own.

No it just reminds me of the tattoo from Mirror's Edge.
