Product looks too superimposed. How can I make it look more realistic

[spudsnruf]

Hi, i'm trying to make the image of the outdoor fire that I have dropped on the background look more natural. It looks too superimposed doesn't it? I've tried the blend modes and the effects options (shadows etc), but it doesn't really help make it more natural. Any guidance please? Thank you very much.

Adjust the shadow on the fireplace - it's noy right and decrease the intensity.

Fireplace needs more saturation and darken the front panelling.

I think the burn tool would save a bit of time select just the fireplace for it set the tool at about 50% on midtones

Thanks very much again. I think the combination of suggestions has (once again) resulted in something that is a lot more plausible. Much appreciated.
