Updates 75 and 38 Gallon

Any opinions on changes to the aquascaping to either tank? The big piece of driftwood in the 75 is still leaching so the rocks toward the back have to hold it down. anything I should add, remove, or move to make look better?
 
I love the driftwood in the first tank!!
The second tank looks very nice, but a nice solid background (imo) would make the colors pop!!
 
wow... cool tanks! as i am a big fan of heavily planted tanks and have a couple going i am a bit biased and think they both would look even better planted from one end to the other.. haha
 
Just curious.......when you clean your tank do you have to move everything out? It looks like it would take a long time.
