I feel like there’s a few things to improve with this image. First off, it’s too blurry. Second, the lighting seems to draw the viewers gaze to the far right, and not the intended focus of the image. Third, there’s a lot of unused space in the image, the left and right sides have nothing in them, it makes me wonder why they’re shown. Finally, I think the posing could be improved, there’s not much life to the scene right now.
 
Other than that though, your way of positioning everything doesn’t obscure any details, which is good.
