I want to suggest glow effects on asteroids. Those could be done on the golden parts at the Veldspar asteroids, for example.
Totally support those idea, but with a minor hint: Not on Veldspar Roids. People should have a motivation to leave HighSec and begin their real adventures, not only financially but also immersion-driven. So please spare the real stunning graphics, effects and breathtaking views for Low-Security Asteroid Belts in Lowsec, 0.0, WH, Pochven… If someone dares to go ninja mining in Lowsec or 0.0, he should get a view presented that nothing in HighSec can rival, so he tells all his comrades about it and that they have to see that.
