wow, this image kinda reminds me of the end of the first unreal. The rocket you've boarded to escape from the planet is now stuck in space and is out of fuel and you have to wait for someone to come and find you.
this scene reminds me of that near perfectly. minus the rocket.
Very nice! Though, the lightsource could be better because it is missing more glows and the rays are showing too clear! Also the planet could have more detail on both lightning and clouds ( just a bit!) I thought I should set some critiques cuz I do these kinds of stuff and hope you don't mind BTW i like the gas giant
