looks good, and im not one to often say that. if i can offer two things you may consider if ever doing this again. add a primer to the frames and window frame so that they evenly match before color, and you might look into the new, widely available, fine textured rattle can paints. they give an amazingly nice look just not quite as rough.
being a design student ,and very literally being trained to see these things, i complement you on what appears to be a fine masking job!
like i said this is a great project. awesome!
