Hi,
for the first job it is okay. Some deatails I would improve.
The background is too saturated, and the chimney including TV does not have any detail anymore.
The contrast is too high. Most of the parts are completely black Maybe you make an interiorlight. Play with the exposure.
The fire is great.
It is a big advantage, that you can already during the rendering improve your settings in the postproduction. I love it.
Keep on going.
