The young guy with the bow and arrow looks uncomfortable, he's not holding the bow right. pretend that you're holding a bow and take a picture to reference from. Its almost as if he's handing up to someone.
As for the fellow in the middle, his left arm is awkward. It looks like the sword has no weight to it. Turn is hand so the palm almost faces the ground. That way if anyone jumps out of the bushes he already has a guard up and can strike back with the other hand. Also the blade/hilt doesn't line up with the handle.
And I second all the things pointed out previously.
"Astronomy offers an aesthetic indulgence not duplicated in any other field. This is not an academic or hypothetical attraction and should require no apologies, for the beauty to be found in the skies has been universally appreciated for unrecorded centuries."
