I looked at this several times - the sun light seems too harsh and the colors too saturated. Needs also maybe some DOF.

oops - just noticed you deleted the image :oops:
well, my comments still stand. :D

Make sure that the transparent parts of your image are perfectly clean/clear.

Play with intensity/power of light emitter to result you want with your render setting and exposure setting.
I would use a very small box with the fire in it in a seperate SketchUp scene for test rendering/adjusting the settings to save time in your experimentation process.
Using point or spot lights to enhance the lighting effect of the fire is important, as you are doing. Point lights may be better in this case than spot lights.

Easiest is to open the spherical sky image into an image editor like photoshop, and change the size of the canvas (not image size) to be 2x in height and width of the original image. Then duplicate your image and it should be seamlessly side-by-side in the middle. then copy the color of the sky and past it in the area above the image, and copy the color of the ground and use it to paint below the image. Or if you have Photoshop or 2021 or later you can use the content aware fill to fill the top and bottom in a way that matches the original image automagically. It works very well.
