JK's notes:
I would throw away the rulers though - lines are too straight-that makes things look mechanical and cold - give the house some weight and make it a bit more organic
and you still are filling up negative spaces
your tree in the bg has nice second level leaf clumps, but the tree iis filling up the space between the house and the fg tree
the bush to the right of the house is eating the house silhouette - if you moved it a bity to the right and left space between it and the house, it would make a better overall composition
look at some of the comic examples I post for less mechanical lines and forms
