The actual royal menagerie in Ala Mhigo is beautiful. I wish they'd add some of that coloring into the Goblet. Goblet remains my favorite residential district, but it has another layer of potential they can tap into, and I'd think it wouldn't be improbable to make the kinds of adjustments I'd suggest.
Adding just a little colorful veggies/bushes and some eye catching tile work would really liven it up a little more.
