Add a gable over the middle two windows and modify the siding under it - maybe vertical or shakes. Dont know if it is vinyl on the top half, but paint the lower half to match, including the brick. Any chance you could bring back the second garage? If not - fir out the opening so it's not so obvious and add in a larger window in that space. You could also add some patio space in front of the converted garage and the next window to the right to mitigate that spot a bit.
