Looks pretty nice. The Jungle Val will get much too big for your tank and it will try to overtake the tank. Good driftwood can be found on ebay, rocks try your own backyard

. I live on an old floodplain so rocks are easy to come by, just go pick the fields. I can't driftwood or rocks from the river where its close to us though

, oil spill up stream of us a few years ago. Lots of rivers around though. Post another picture when it fills in more.
