Hi Jacob -
The “no gi” image is the one that looks much too yellow. Try a less saturated key light color, more similar to the color of the sun in the background image. Also, you might try using a directional light for the direct sun, so that the shadows will be more parallel. Be sure your Ray Depth Limit is high enough that shadows appear in reflections, they are missing inthe wine bottle now. There’s something strange to investigate about the front surface of the window frame - is it a reflection?
The “gi, no fg” image looks pretty good. The bottom of the fruit plate and the paper towels are going too bright, you might adjust the shaders involved. I can’t figure out what happened to the inside of the window frame, it was super-bright-yellow without GI, now you turn on GI and it’s dark blue? Investigate that.
The “gi and fg” image looks pretty good. Some of the front-facing surfaces are going too bright, as if there’s something really bright behind the camera. You might invesigate that.
