I would paint the beige and dark gray sections the same color as the stucco. Remove the hedges and work on the grass. You could also paint the brown trim on the balcony roof to the stucco color to make it less obvious

I have a California bungalow, too!

Casements would be a great idea to bring those "big 3" down to scale.

I think a simpler color palette would be much more suited to what you're going for. How about just 2 colors? The house one color and the trim another? Paint the "flat" areas under the eves the same color as the stucco (that dark area under the left windows, too). Then paint all the dark brown areas the same color as the "raised" decorative pieces AKA trim (a lighter color than the stucco). Is that dark thing under the left windows something that can be removed? .

The shrub looks healthy. How about trimming it to about half it's current height and taking a little off the sides? You'd still have some established greenery, and more of your home would be visible. It would even out the proportions and look great!

Have fun and good luck
