Lighting Key

Here is my photoshop drawn version of my idea for lighting.  Also, I have some images I found of sunny kitchens for reference.  I would like this too look like a sunny morning in an inviting and warm kitchen.

I like the pool of window light on the floor in the image above.

I like the overall lightness and cheeriness of this image.  

I like the gradient of light on the wood floor in this image.
