It looks good Chris.
Sort of draws you in.
One day the colours will appear. Play around with stretching (developing, histogram transformation, DDP for Nebulosity I think).
Be mindful of overexposure (you lose colour).
Play around with the camera settings and learn.
I don't use Nebulosity, but this looks good:

Well done.
