First, paint the soffit, bridge & ceiling bright white in a FLAT finish. I hope you are not painting the walls in a semi gloss finish. Switch to eggshell for the walls
I would not keep the blue of the walls. It makes the oak appear too orange.
Below is the color I was trying to show in the photo, but the color was altered because of the yellow of the oak.
That plywood front for your peninsula is not attractive. I would face it with battens to create more interest and then paint over the plywood and the battens.
