I think the fire is misplaced and not fitting it.

The renders for me are cold, you can make an abstract effect with blending fire in, but then "Blend" it in, not just put it there.

Also, try to think of a setting before you make something instead of "just" doing something.

Idk whether to remove the necklace or just fix the fire.

I don't think the element fire fits the render, the necklace is going to be rough for you so you'd be better off removing it. But if you want to improve your skills then keep trying...

You can use a small eraser and make the necklace stand out. You should also use gradient layers or photo filters to add some color and maybe even re-color the fire accordingly.

So, You basically put the render on it, put some c4d's on it, edited and done?

I don't even know why I use that signature, been made 2 years ago, when even I did that kind of stuff too.
And nope, most backgrounds are made by yourself.
