At this point I have a few ideas of what I could be doing with LDD.
Build more Future Era Transformers such as:
Mindjack
Fidelis Prime
Bushwhack

Build more Clash of Legend Transformers such as:
Trick Box
Bahumut
Tiamat

Build more Star Trek style ships such as:
Klingon-esque Ship
Romulan-esque Ship
Another Federation Ship

And others if you watchers have suggestions
