I have followed each steps as instructed. I wonder why after last compositing step, my render results still not as I expected. I attched my result as follow.
Good thing it was not an error, there's nothing to worry about. If you hadn't pointed at anything I would've said everything looks good, the problem is that it's not what you are after, so it's just a preference issue. You can always adjust some parameters and lighting to get different results and achieve what you are after. Your planet render looks great, so good job.
