Veles Colony:
The colony needs more NPC life. I’d suggest adding some NPCs with patrol routes, like patrolling guards.
Maybe have a few vermin spawn in appropriate locations, like Mynocks near energy sources or Womp Rats near garbage piles.
A cantina near the starport would be great. It doesn’t have to be big, but it will give new players an easily recognizable area where they might meet others.
Another thing is “mission terminals”. Those could be useful to provide players with daily quests like deliveries, bounties, crafting or gathering to help players make money.
I don’t think there needs to be a huge variety of daily quests, but having a couple would be good. This is especially important for players who aren’t going to be crafters themselves.
Edit: If you plan on redoing Veles Colony, it might be a good idea to split it into 2 or 3 smaller areas (for example a residential district and a commercial district).
Viscara
Wildlands, Mountain Valley and Deep Mountains need some variety in enemies. Perhaps some vermin near the Caxxion refinery or malfuncting maintenance droids.
Having a few caves in approriate areas might also be a good idea. They could contain crystal and ore nodes or they could be creature lairs like a Kath Hound den, etc.
Wildlands need more Fiberplast nodes
