EEVEE render
First off, a wonderful piece of work. I do offer a small critique. Almost all of your scene looks great however a couple of items seem to me to be out of scale. Your stack of blue barrels looks in scale to the scene. The two barrels in the middle of your scene, the Elf and the mostly red barrel in real life would be roughly the same size as the blue barrels in your stack. In the scene the Elf barrel looks larger than the blue ones even though it is farther away. The two other barrels nearer the blue barrels should be brought down smaller to relate more to the blue barrels. Thank you ever so much for a great little scene.
Amazing
