The posing and scene objects looks good like the falling structure is there a reason why the image is a little faded blurry around the background?
The lighting and elements put into the scene makes it pop, perhaps try including more space objects more stars and other useful planets if ever needed the background has a bright appearance I’m assuming that’s casting because the amount of effects you put into it or the lighting? Since you’re still learning this could take into consideration when approaching a new project.
You should decrease the amount of white lighting shining on the character face. it’s decent but a few touches could go along way.
