That's quite the change from the original layout. Can barely even tell you have the rock or wood in there and it doesn't even look hilly. The 12MP camera definitely takes a clearer pic compared to the first camera you used. That may be due to some of the adjustments on the camera though as I use an 8.2 MP camera to take shots of my tank and they come out pretty clear (unless the fish are moving). Try messing with the buttons on your original camera and see what happens.
