Yeah, if the shadows are darkened a bit, it'll look spot-on.
The ceiling still doesn't match, though, which has bugged me since I first saw ESB (before the SE, there was a skylight ... but another floor above Leia ... )
I think the best thing to fix that is to just move the whole window slightly to the right, then move the interior slightly more to the right. That way, it won't look drastically different, but it'll help the ceiling match the roof at the same time.
