It’s much more, but I don’t think you emphasized how bright the fire actually is unless if the alien’s skin just doesn’t have as much specular.
You could also add shadows between the wood on the campfire as well as some additional shadows under the alien’s arms and in the areas where the light isn’t present.
Same thing could be done with the hills in the background.
The distant mountains should blend into the skys color a bit more, unless if its an extremely bright light source somewhere. If there is then emphasize that more. You could also add a shadow behind it if its the comet’s light.
