I don't mind the lines, but maybe you should make them softer to join with the rest of the composition's soft texture. I love this. It's got a really lovely calm feeling to it and you can really see the way the sunlight dances on the side of the window.
I'll post a link to the house. Note though, that I used different parts of the three windows at the bottom and combined them to make one window that had all the properties I wanted for this one window, so this window will look familiar to the windows in the ref, but not a literal copy of any one of them.
