Hey, it's looking pretty good! Here are a few tips to keep in mind when working with Eevee. Remember that your scene can look "almost" as good as Cycles, but it will never be quite as good. The biggest difference comes in the reflections, refractions, and shadows (basically, the parts that Cycles would typically raytrace). Have a look in my Gingerbread Man Dance thread for some comparisons I made between the two engines on the same scene.

Anyway, you will definitely want to make sure all the bells and whistles are activated in Eevee for best results. This means, obviously, Ambient Occlusion and Screen Space reflections are important. However, there are a few tricks when it comes to reflections and refractions that will help you.

First, be sure you UNcheck the "half trace" option. It is enabled by default. This reduces the quality of your reflections for the sake of speed. You do not want that checked if you are looking for higher quality results.

Second, there are some settings that will play a role on some of your materials that have reflectivity or roughness. Under Screen Space reflections, be sure you increase trace precision if you want higher quality reflections. The default is very low. I typically set this to 1. If you have roughness on your materials, then increase the Max Roughness setting. By default, that is also set very low, which will limit the roughness of your reflective materials to a minimum value. You can increase this with minimal impact to speed.

Third, under Performance, make sure you are using "High Quality Normals". This is not enabled by default. This will use higher quality normals and tangents on materials with normal maps, which will also help improve scene quality at the expense of some minimal render time.

Fourth, under Shadows, make sure High Bitdepth is being used. And then increase the shadow map size to at least 2048px for both cascade (distant sun) and box parameters. This will increase shadow quality for your lights at the expense of some render time. I usually crank these values to 4k, but it depends on your GPU.

Finally, make sure if you have any refractive materials that you enable that option in Screen Space Reflections area, but also it needs to be enabled PER material. If you have glass materials, then select that material, scroll down until you see "Screen Space Refraction" parameter under the settings rollout for that material, and check it. Then change the Blend Mode and Shadow Mode to Hashed for best results.
