The kitchen is amazing. I love the breakfast bar and the opening from the kitchen to living room. Great graphics! However, the elevation does not show the existing roofline which initially made me discount your work all together. After putting it into perspective I realized that the sun hole could fall in-line with the existing roof line. When using visual representations like maps or in this case residential designs there should be no question or confusion as to the message the designer is attempting to convey. In this case something so simple as a roof line is a major part of your design creativity.
