the Dutch Colonial that I’m working on
Doug both of your buildings look even better in real life! The front of this Dutch colonial looks fantastic.
One comment that experienced builders often point out is the need to get rid of the staircase pattern seen when along the edge of roof made by sloped bricks. I’ve learned that its possible to cover this staircase pattern with long 2x plates attached sideways to the roof line. You might try this with a couple of headlight bricks or a technic brick with a short pin sticking out. Only certain intervals match along this diagonal, so you have to play with it a bit.
Of course, the Dutch colonial roof has two different roof angles, so that would be even trickier to hide. Another option is to use inverted bricks but they tend to make a very thick roof. All of this would be easier if they made more of this piece, but I have only seen it in black:
