Sorry for the small size; that by itself took more than 10 hours at 0.9 detail. It at least gives an idea of what it looks like. I will be trying to render a larger version in the future though when I don't need my computer for a while.
Its all Terragen except the flare from the sun.
Wonderful clouds! Your planet looks pretty intimidating ;). Next time I would go with less lens flare - I feel like the amount you've got is a bit too distracting.
It really looks good. Try settings of 0.5 quality and then compare both renders.
They might be different - but is there really more detail !?! for an objective viewer!?! ;)
Name? 'Red Embracing' - just the first thought
