My grandpa has been a blooddonor for over twentyfive years and I want to be an donor as well. So I created a story based upon this thought. 

I will explain the story later. But I wanted a cover, that had something to do with this idea. (Because thats the purpose of a cover... Duh...)

I created a few, but I don't know which one I like the best.

I like this one, because it reflects the idea pretty well. 

Or this one. Which is maybe better, due to the actual bloodflow. But it is more creepy and the story shouldn't be creepy.

This one is the same as the first, only I moved the letters. I don't like this as the fist two. It feels to empty.

And lastly this one. I've the same problem with this as the previous. It feels to empty.

So... let me know which one fits best!

(By the way... the story is originally dutch... The title is Bloodbond (As mentioned in the title))

Excerpt:

Nathan has Hypovolemia. Which means he doesn't have enough circulating blood. To make matters worse he has the rarest blood type: AB-.

Devin lost a challenge with her friends and now she has to donate blood. Her bloodtype is AB-. She's asked to donate blood to Nathan directly. They spent every week at least hour with each other.

Devin dislikes Nathan for his childish behavior.

Nathan dislikes Devin for her bitchyness. 

And yet... a friendship grows.

So now you get the story. Which cover fits best?  Let me know in the commentsection below!
