“End of the Line” cover art update #4

Man… what the… Trevor Smith is killing me. I just received TWO possible covers from him. Take a look:

"End of the Line" concept cover art - 3 Marines

“End of the Line” concept cover art – 3 Marines

"End of the Line" concept cover art - Through the Scope

“End of the Line” concept cover art – Through the Scope

 

Top picture – “Three Marines”
Bottom picture – “Through the Scope”

So… my dilemma is… which one? I’m actually thinking of asking Amazon if I can offer alternate covers, and if not, use one for the ebook and the other for the print paperback. What do you think?
