Everything seems to emit light, but not enough of it. The fire seems somewhat out of perspective and instead of casting light directly onto the alien its acting as if it’s on the other side in which it does not look like so. It also should be emitting more light on the wood and a bit on the ground (if you wanna go as far as detail with that) the comet could also use a bit more emission. Add some of its light on the hill and a bit on the alien.

After all that, It’d be enjoyable.
