Very nice looking bonsai, and this is coming from someone who barely eats vegetables, let alone looks at them.
If you put up more album covers, aren't you afraid that it will turn out too crowded with the bonsai there as well? I think the simplest designs usually turns out the best, so look out for that if you do decide to put up more. I'd much rather actually take off that pic (album sleeve?) that is there already and let the bonsai have some breathing room.
