Basically any planet or timeline from the new series is a good answer, but do keep in mind I'm mostly an environment artist, so locations with a lot of people running around might not work out so well. I do plan to build some Daleks soon, though.
Most poll options are things I was thinking of. For "other" feel free to post what you'd like down below!
Asylum of the Daleks
Rings of Akathen
Planet of the Ood
