Great blending but I think some background would be better than just plain black one
Sorta along the same vein as the famous Tiananmen square image, black isn't bad, but there are different shades of it on my monitor down the left side where it looks as if maybe you tried to paint it in....
Funny stuff and a good imagination. Now we know where Thing is working from the Addam's family...hehe I would probably darken those light areas on the edge of handle a little, since there's no light coming from the back of the kettle.
To me, it looks to be floating over the burner instead of sitting on it. There is some pesky masking debris or a hard edge at the bottom too. Notice the silver pot behind it. See the lighting effect it has. The Kettle should have the same effect. Also maybe add a little gaussian blur to the kettle to match the sharpness of the whole image.
