I think you should add a glassy cover to the spaceship. Right now it appears like the crew is on some floating flat metallic lamina.
Also consider scaling up the spaceship when it lands on the planet because it appears so tiny compared to the soldiers.
The ending is a bit ambiguous. The monster kills a crew member and... it's over. I think you should elaborate it more and continue the cinematic until, for example, the crew leaves the planet safely or they all die.
