I get what you've tried to do here (shoot wide to show all the machines and a bit of the surrounding for perspective), but it doesn't work in this case. Actually this is a fairly common noob mistake (and something I still do too much as well), trying to show 'too much' in the one shot. In cases like this, less is more - if you got in closer and don't necessarily try to fit all the machines in the one shot it would help, but I think the main thing to improve here is angle. You can show the size of these beasts without including any of the background/foreground (which is sort of ugly in this case) by changing the angle of the shot.
Keep shooting!
