Looking good for a start. Reminds me a lot of my new 60-P in development =)
Obviously, you can develop your back and mid ground some. Do you want to incorporate any color differentials? You can still go a lot of ways with the scape. Your plant selection will be both subjective and somewhat dynamic- it's up to you to scape as you wish.
However, if going for the full show tank look, ADA-esque, bad-ass look, I'd swap that plastic in take (and other out take I can't see) with Lily pipes or other (Do!Aqua, other knockoffs). I live in the Bay as well, in SF, on the the 22 MUNI line which drops me off right in front of Aqua Forest Aquarium. I am spoiled, but appreciative. It does make it hard to be discretionary so my wallet doesn't suffer =)
I'm also in the process of setting up a show quality 60-P for my living room and working though the daily dilemmas (Algae, CO2 levels, trimming, fert mix/schedule) to keep it evolving according toward my vision.
Keep it going! Lookin good.
