Don't be too critical about the layout just yet; give it a few weeks to fill in and get established. As for the 'fake' driftwood, if you attach some java ferns, Bolbitis, or Anubias to it you won't even see it in a few months!
For now just work on adjusting you light and ferts and relax!
FYI, attaching a black plastic background
to the back of the tank would help the asthetics by hiding the wall, wires, etc.
